* 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.

* vmalert: make default timeout for sending alerts 10s
Previous value of 1m was too high and was inconsistent
with default timeout defined for notifiers via
configuration file.

* 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.

This allows filling the seriesCountByFocusLabelValue list in the /api/v1/status/tsdb response
with label values for the specified focusLabel, which contain the highest number of time series.

vmalert: support `limit` param in groups definition
`limit` param limits number of time series samples produced by a single rule
during execution.
On reaching the limit rule will return an err.

dd-agent v5 can issue some requests with trailing slashes.
(e.g.
526559be73/ddagent.py (L303))
Trim trailing slashes for request on /datadog/ paths to accomodate for
that.

- 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
```
