### Describe Your Changes
Corrected spelling mistake in the operator json to be "working" instead
of "wokring"
### Checklist
The following checks are **mandatory**:
- [ x ] My change adheres [VictoriaMetrics contributing
guidelines](https://docs.victoriametrics.com/contributing/).
This should improve precision of `restarts` and `version change` annotations when
zooming-in/zooming-out on the dashboards.
The change also makes `restarts` dashboard visible on the panels, so user can disable it from
displaying if needed. This could be useful when restarts overlap with version change events.

The error appears when executing annotations query against Prometheus backend
because the query itself hasn't specified look-behind window (which is allowed
in VictoriaMetrics query engine).

The panel will show how many ongoing select queries are processed by vmstorage
and should help to identify resource bottlenecks. See panel description for more details.

Allowing to select multiple instance IPs makes it much easier to view
metrics for longer periods of time in dynamic environments such as
Kubernetes. In k8s update will also cause IP to change making it harder
to use dashboard to check the status.

The cumulative number of active merges could be red herring
as it its value depends on the number of vmstorages.
For example, vmstorage could be added or removed and this will affect
the panel.
Or, each vmstorage could start a merging process (i.e. for downsampling)
and visiually it could look like a massive change.

During background downsampling, rate(vm_deduplicated_samples_total{type="merge"}) could be much bigger than
rate(vm_rows_added_to_storage_total) and it could last quite some time,
which causes negative values of Storage full ETA and confuses users, see playground.
Instead of trying to get more accurate results during downsampling, I think it's ok to ignore
vm_deduplicated_samples_total at all, it's more reasonable to see Storage full ETA increase after downsampling.

It should help identifying cases when too much CPU is spent on garbage collection,
and advice users on how this can be addressed.

* add panels for detailed visualization of traffic usage between vmstorage, vminsert, vmselect
components and their clients. New panels are available in the rows dedicated to specific components.
* update "Slow Queries" panel to show percentage of the slow queries to the total number of read queries
served by vmselect. The percentage value should make it more clear for users whether there is a service degradation.

* vmagent: export `vm_promscrape_scrape_pool_targets` metric to track the number of targets that each scrape_job discovers
* add extra panel for new metric
The `path!="/favicon.ico"` filter has little sense, since there are many other special paths,
which may be filtered out - /metrics, /flags, /health, /ping, /robots.txt, /-/healthy, /-/ready, /reload, etc.
See /lib/httpserver/httpserver.go for more details.
It will be hard or impossible to maintain filters for all these paths, so it is better to drop this filter
in order to simplify queries and improve the consistency of these queries.
`version` label won't show the difference if various flavors of the same
version were deployed. But `short_version` will.
For example, on the sandbox env we test VM builds before new version release.
Without this change, the version update won't be visible on dashboard.

The panel `Errors rate to Alertmanager` had `group` label filter
applied to the expression, while the metric `vmalert_alerts_send_errors_total`
doesn't have that label. This resulted into always empty results.
