querytracer has been added to the following storage.Storage methods:
- RegisterMetricNames
- DeleteMetrics
- SearchTagValueSuffixes
- SearchGraphitePaths
Metrics `vm_partial_results_total` and `vm_requests_total` serving
the similar purpose, but contain inconsistent set of labels.
This change updates `vm_partial_results_total` labels to be consistent
with `vm_requests_total`.
The change breaks backward compatibility with assumption that
`vm_partial_results_total` wasn't widely used, since it is
not documented and absent in the alerts and dashboards.

Previously the processVMSelectDeleteMetrics was calling separate functions from readSearchQuery().
It is better from readability and maintenance PoV to substitute it with readSearchQuery call.
* vmalert: remove head of line blocking for sending alerts
This change makes sending alerts to notifiers concurrent instead
of sequential. This eliminates head of line blocking, where first
faulty notifier address prevents the rest of notifiers from
receiving notifications.

* vmselect: limit `end` param max value by 2d in future
The change is applied only to service handlers like `/labels` or `/series`
and limits the `end` param by max value <= now() + 2 days. The same limit
is applied for the ingested data, so no reason to allow to request data
in future far than that.
The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669
where too high `end` value triggers inefficient global index search.

- Remove unused js bloatware from /targets page. This strips down binary size by more than 100Kb
- Add /service-discovery page for API compatibility with Prometheus
- Properly load bootstrap.min.css from /prometheus/targets
- Serve static contents for /targets page from app/vminsert instead of app/vmselect, because /targets page is served from there
The default size of `indexdb/tagFilters` now can be overridden via
`storage.cacheSizeIndexDBTagFilters` flag.
Please, be careful with changing default size since it may
lead to inefficient work of the vmstorage or OOM exceptions.

Fixes security vulnerability in nth-check version <=1.0.2
My previous version pin was insufficient, as it was imported again through a different (svgo -> css-select).
The new metric shows the configured evaluation interval per group.
Metric updates its value when group's interval is changed during
hot reload.
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

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`.

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.

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.

to InfluxDB v1 via remote_write.

make sure we are not skipping it and everything afterwards.

This adds a metric for the rate limit.
The limit is present as a flag currently:
`flag{name="remoteWrite.rateLimit", value="500000", is_set="true"} 1`
We are running many instances of vmagent and when creating alerts it is harder than it needs to be when extracting the value from the flag.
With this change it should be easier to monitor how close to the limit we are.
`((100/vmagent_remotewrite_rate_limit{account="account"})*sum (rate(vmagent_remotewrite_conn_bytes_written_total{account="account"}))) and ON (account) flag{name="remoteWrite.rateLimit"} == 1`
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.

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.
