Suggest `-search.maxStalenessInterval=10s` instead of `-search.maxStalenessInterval=1ms`,
since `1ms` would result in empty graphs in most cases, since the interval between data points
on the graph is usually much higher than 1ms. For example, if the graph shows time range of one hour
and it contains 1000 points, then the interval between points on the graph would equal to
3600s/1000=3.6 seconds.
* feat: make datepicker to be set to last 30 min by default
* fix: correct spinner while loading data
* feat: change legend style
* app/vmselect: `make vmui-update`

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.

The change updates histogram for registering SD update duration
only SD is considered as `active`. SD is active if at least
one scraper for this SD has started.
This change supposed to reduce metrics cardinality produced
by duration histogram which gets updated even if SD isn't configured.

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.

Workers count for merges affects the max part size during merges. Such behaviour
protects storage from running out of disk space for scenario when all workers
are merging parts with the max size.
This works very well for most cases. But for systems where high number of CPUs
is allocated for vmstorage components this could significantly impact the max
part size and result in more unmerged parts than expected.
While checking multiple production highly loaded setups it was discovered that
`max_over_time(vm_active_merges{type="storage/big}[1h]}"` rarely exceeds 2,
and `max_over_time(vm_active_merges{type="storage/small}[1h]}"` rarely exceeds 4.
The change in this commit limits the max value for concurrency accordingly.

- 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
- Take into account `ca`, `key` and `cert` values when generating string representation of TLSConfig.
Print hashes instead of real values because of security considerations.
- Properly update Config.tlsCertDigets when `key` and `cert` values are set.
This allows properly updating scrape targets after these values are updated in configs.
- Do not re-generate certificate from `key` and `cert` values per each call to getTLSCert,
because these values are immutable.
- Do not set `ca` value from `ca_file` value, so it isn't exposed at `/config` page.
- Generate proper error messages on incorrect `key`, `cert` or `ca` values.
