http server: limit max concurrent requests (#4185)
* lib/httpserver: introduce `-http.maxConcurrentRequests` command-line flag

Introduce `-http.maxConcurrentRequests` command-line flag to protect
VM components from resource exhaustion during unexpected spikes of HTTP requests.
By default, the new flag's value is set to 0 which means no limits are applied.

app/vmselect: follow-up for 10ab086366
- Expose stats.seriesFetched at `/api/v1/query_range` responses too
  for the sake of consistency.

- Initialize QueryStats when it is needed and pass it to EvalConfig then.
  This guarantees that the QueryStats is properly collected when the query
  contains some subqueries.

vmalert: support logs suppressing during config reloads (#3973)
* vmalert: support logs suppressing during config reloads

The change is mostly required for ENT version of vmalert,
since it supports object-storage for config files.
Reading data from object storage could be time-consuming,
so vmalert emits logs to track the progress.

However, these logs are mostly needed on start or on
manual config reload. Printing these logs each time
`rule.configCheckInterval` is triggered would too verbose.
So the change allows to control logs emitting during
config reloads.

Now, logs are emitted during start up or when SIGHUP is receieved.
For periodicall config checks logs emitted by config pkg are suppressed.

app/vmalert: do not wait for group start on removal (#3891)
Each group in vmalert starts with an artifical delay to avoid
thundering herd problem. For some groups with high evaluation
intervals, the delay could be significant.
If during this delay user will remove the group from the config
and hot-reload it - vmalert will have to wait until the delay
ends. This results into slow config reloading and UI hang.

The change moves the start-delay logic back to the group's
`start` method. Now, group can immediately exit from the
delay when `group.close()` method is called.

vmalert: cancel in-flight requests on group's update or close (#3886)
When group's update() or close() method is called, the group
still need to wait for its current evaluation to finish.
Sometimes, evaluation could take a significant amount of time
which slows configuration update or vmalert's graceful shutdown.

The change interrupts current evaluation in order to speed up
the graceful shutdown or config update procedures.

vmalert: speed up state restore procedure on start (#3758)
* vmalert: speed up state restore procedure on start

Alerts state restore procedure has been changed to become asynchronous.
It doesn't block groups start anymore which significantly improves vmalert's startup time.
Instead, state restore is called by each group in their goroutines after the first rules
evaluation.

While previously state restore attempt was made for all loaded alerting rules,
now it is called only for alerts which became active after the first evaluation.
This reduces the amount of API calls to the configured remote read URL.

This also means that `remoteRead.ignoreRestoreErrors` command-line flag becomes deprecated now
and will have no effect if configured.

app/vmalert/templates: properly escape all the special chars in quotesEscape function
Previously the `quotesEscape` function was escaping only double quotes.
This wasn't enough, since the input string could contain other special chars,
which must be escaped when put inside JSON string. For example, carriage return and line feed chars (\n\r),
backslash char, etc. This led to the following issues, which were improperly fixed:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890 - this issue
  was "fixed" by introducing the `crlfEscape` function, which led to unnecessary
  complications in user templates, while not fixing various corner cases
  such as backslash chars in the input string.
  See 1de15ad490

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 - this issue
  was "fixed" by urlencoding the whole string passed to -external.alert.source
  command-line flag. This led to invalid urls, which couldn't be parsed by Grafana.
  See 00c838353d
  and 4bd0244599

This commit properly encodes the input string passed to `quotesEscape`, so it can be safely embedded inside JSON strings.

This commit deprecates crlfEscape template function and adds the following new template functions:

- strvalue and stripDomain - these functions are supported by Prometheus, so they were added
  for compatibility purposes.
- jsonEscape and htmlEscape for converting the input string to valid quoted JSON string
  and for html-escaping the input string, so it could be safely embedded as a plaintext
  into html.

This commit also documents all supported template functions at https://docs.victoriametrics.com/vmalert.html#template-functions
The deprecated crlfEscape function isn't documented on purpose, since its usefulness is negative in general case.

Revert "vmalert: escape query params if external alert source defined (#3267)"
This reverts commit 00c838353d.

Reason for revert: it incorrectly fixes the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 .
Now `-external.alert.source=explore?orgId=1&left=...` is converted to the following invalid url, which cannot be handled by Grafana:

https://grafana.example.com/explore%3ForgId%3D1%26left%3D...

The next commit will contain the correct fix of the issue - the `quotesEscape` function must
properly escape the string, so it could be embedded into JSON string. This function must
properly escape \n\r chars too. In this case the `crlfEscape` function becomes unnecessary.
Actually, the next commit makes the `crlfEscape` function deprecated.

vmalert: allow using extra labels in annotations (#3181)
According to Ruler specification, only labels returned within time series
should be available for use in annotations.

For long time, vmalert didn't respect this rule. And in PR
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2403
this was fixed for the sake of compatibility. However, this resulted
into users confusion, as they expected all configured and extra labels
to be available - https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3013

This fix allows to use extra labels in Annotations. But in the case of conflicts
the original labels (extracted from time series) are preferred.

vmalert: set default value for datasource.queryStep to 5m (#3149)
Change default value for command-line flag `datasource.queryStep` from `0s` to `5m`.
Param `step` is added by vmalert to every rule evaluation request sent to datasource.
Before this change, `step` was equal to group's evaluation interval by default.
Param `step` for instant queries defines how far VM can look back for the last written data point.
The change supposed to improve reliability of the rules evaluation when evaluation interval
is lower than scraping interval.

vmalert: always re-evaluate Annotations (#3119)
* vmalert: always re-evaluate Annotations

Previously, Annotations were evaluated only:
1. On alert creating.
2. On alert's value change.

This is premature optimization. It was assumed that since annotations
could contain only text with alert's labels or value - there is no need
in spending resources to re-compile Annotations.

Later, template function `query` was added, which can execute
arbitrary queries and return different results on every evaluation.
So if it was used in annotations, it would be executed only on init
or value change.

Another case when optimization caused an issue - annotations hot reload.
In this case, annotations of the active alert won't change even if Rule's
annotations were changed.

This fix enables Annotations re-evaluation on each iteration to resolve
issues above. It would have some impact on performance, but it is unlikely
it will be noticeable.

The new metric can be used to estimate how close group
is to start missing evaluation rounds. The following query
will show the % of used time by the group to evaluate all rules
before the next round:
```
(max(vmalert_iteration_duration_seconds{quantile="0.99"}) / vmalert_iteration_interval_seconds) * 100

vmalert: support /rules path for Grafana's ngalert requests (#2593)
Unexpectedly, Grafana makes an extra request to `/rules`
handler in addition to `/api/v1/rules` calls in alerts UI.
This happens only for Grafana versions older than 8.5.*.
Apparently, this is related to support of other monitoring
systems.
Prometheus responds with `text/html` content for UI page `/rules`
to such requests. Actually, returning just a blank page with
SC=200 works as well.

Returning actual response of `/api/v1/rules`
results in error in Grafana since it expects a `yaml` (?) in response.
So we add a placeholder to `vmalert`.

docs: fix liquid syntax errors (#2592)
For liquid text processor double braces `{{` `}}`
are special chars for templating.
Since we use them in some of our docs with different purpose,
we must escape them to avoid syntax errors from liquid.

For escaping curly braces we use bult-in plugin which helps
to enclose sections of text via `{% raw %}` and `{% endraw %}`.
This approach prevents liquid syntax errors and makes render correct.

vmalert: properly cleanup stale series tracker on rules update (#2577)
Rules executor within group tracks series sent to remote write
in order to mark them as stale if they had disappeared in next
evaluation round.
The executor uses rules ID as a key to identifies series which belong to rule.
On config reload, executor remains active but the set of rules could change.
Hence, we need to properly cleanup the tracker for rules which has been disappeared
on config reload.

vmalert: do not execute templates during validation (#2528)
Function `ValidateTemplates`, used on the vmalert startup,
is supposed to check whether used templates and functions
in loaded rules are correct. The function was parsing
and executing loaded templates.
However, rules may contain functions which can't be executed
without values (label values or query results), like `slice`.
Because of this, validation for completely valid expression
`{{ slice $labels.job 9 }}` will fail since `$labels.job`
is empty during validation.

This PR updates `ValidateTemplates` function to only parse
templates without executing them.

vmctl/vm: added datapoints collection bar (#2486)
add progress bars to the VM importer

The new progress bars supposed to display the processing speed per each
VM importer worker. This info should help to identify if there is a bottleneck
on the VM side during the import process, without waiting for its finish.
The new progress bars can be disabled by passing `vm-disable-progress-bar` flag.

Plotting multiple progress bars requires using experimental progress bar pool
from github.com/cheggaaa/pb/v3. Switch to progress bar pool required changes
in all import modes.

The openTSDB mode wasn't changed due to its implementation, which implies individual progress
bars per each series. Because of this, using the pool wasn't possible.

vmalert: support relabeling for alert labels sent via notifier
Before, relabeling for notifier configured via file was supported
only for target labels discovered via SD.
With this change, new config field `alert_relabel_configs` is introduced
for applying relabeling to labels of sent alerts.

vmalert: fix labels and annotations processing for alerts (#2403)
To improve compatibility with Prometheus alerting the order of
templates processing has changed.
Before, vmalert did all labels processing beforehand. It meant
all extra labels (such as `alertname`, `alertgroup` or rule labels)
were available in templating. All collisions were resolved in favour
of extra labels.
In Prometheus, only labels from the received metric are available in
templating, so no collisions are possible.
This change makes vmalert's behaviour similar to Prometheus.

For example, consider alerting rule which is triggered by time series
with `alertname` label. In vmalert, this label would be overriden
by alerting rule's name everywhere: for alert labels, for annotations, etc.
In Prometheus, it would be overriden for alert's labels only, but in annotations
the original label value would be available.

See more details here https://github.com/prometheus/compliance/issues/80

vmalert: add flag for disabling long-lived connections (keepalive) (#2395)
The new flag `datasource.disableKeepAlive` allows disabling keepalive
connections. This may be useful if there are multiple datasource
replicas (e.g. vmselects) behind the HTTP balancer to avoid uneven
load spread because of long-lived connections.

vmalert: protect executor's field from concurrent access (#2387)
Executor recently gain field for storing previously sent series.
Since the same executor object can be used in multiple goroutines,
the access to this field should be serialized.

Vmalert compliance 2 (#2340)
* vmalert: split alert's `Start` field into `ActiveAt` and `Start`

The `ActiveAt` field identifies when alert becomes active for rules
with `for > 0`. Previously, this value was stored in field `Start`.

The field `Start` now identifies the moment alert became `FIRING`.

The split is needed in order to distinguish these two moments
in the API responses for alerts.

* vmalert: support specific moment of time for rules evaluation

The Querier interface was extended to accept a new argument
used as a timestamp at which evaluation should be made.

It is needed to align rules execution time within the group.

* vmalert: mark disappeared series as stale

Series generated by alerting rules, which were sent to remote write
now will be marked as stale if they will disappear on the next
evaluation. This would make ALERTS and ALERTS_FOR_TIME series
more precise.

* vmalert: evaluate rules at fixed timestamp

Before, time at which rules were evaluated was calculated
right before rule execution. The change makes sure
that timestamp is calculated only once per evalution round
and all rules are using the same timestamp.

It also updates the logic of resending of already resolved
alert notification.

* vmalert: allow overridin `alertname` label value if it is present in response

Previously, `alertname` was always equal to the Alerting Rule name. Now,
its value can be overriden if series in response containt the different value
for this label.

The change is needed for improving compatibility with Prometheus.

* vmalert: align rules evaluation in time

Now, evaluation timestamp for rules evaluates as if
there was no delay in rules evaluation. It means, that
rules will be evaluated at fixed timestamps+group_interval.
This way provides more consistent evaluation results and
improves compatibility with Prometheus,

Vmalert compliance improvements (#2320)
* vmalert: add support for `sortByLabel` template function

* vmalert: update API according to Prometheus conformance program

The changes to the API, field names and URL path has been made
according to the Prometheus specification for `alert_generator`
https://github.com/prometheus/compliance/blob/main/alert_generator/specification.md

* vmalert: fix the timestamp of the evaluated rules

The timestamp used for alert's `EndsAt` was calculated
before sending the notification. While the correct way
is to use the timestamp taken right before rules evaluation.

* vmalert: add `-datasource.queryTimeAlignment` flag

The flag is supposed to provide ability to disable `time`
param alignment when executing rules. By default, this flag
is enabled, so it remains backward compatible.

The flag was introduced to achieve better compatibility
with Prometheus behaviour according to https://github.com/prometheus/compliance/blob/main/alert_generator/specification.md
