vmalert: update retry policy for pushing data to -remoteWrite.url (#4504)
By default, vmalert will make multiple retry attempts with exponential delay.
The total time spent during retry attempts shouldn't exceed `-remoteWrite.retryMaxTime` (default is 30s).
When retry time is exceeded vmalert drops the data dedicated for `-remoteWrite.url`.
Before, vmalert dropped data after 5 retry attempts with 1s delay between attempts (not configurable).

See `-remoteWrite.retryMinInterval` and `-remoteWrite.retryMaxTime` cmd-line flags.

Now, it started to be used and vmalert panics in runtime.

The fix properly inits map for at `NewVMStorage` and verifies it is not nil

app/vmalert: detect alerting rules which don't match any series at all (#4198)
app/vmalert: detect alerting rules which don't match any series at all

vmalert starts to understand /query responses which contain object:
```
"stats":{"seriesFetched": "42"}
```
If object is present, vmalert parses it and populates a new field
`SeriesFetched`. This field is then used to populate the new metric
`vmalert_alerting_rules_last_evaluation_series_fetched` and to
display warnings in the vmalert's UI.

If response doesn't contain the new object (Prometheus or
VictoriaMetrics earlier than v1.90), then `SeriesFetched=nil`.
In this case, UI will contain no additional warnings.
And `vmalert_alerting_rules_last_evaluation_series_fetched` will
be set to `-1`. Negative value of the metric will help to compile
correct alerting rule in follow-up.

Thanks for the initial implementation to @Haleygo

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.

Sort labels explicitly after calling the ParsedConfigs.Apply() when needed.

This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.

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.
