lib/promrelabel: optimize action: {drop,keep,labeldrop,labelkeep} with anchored regex prefix

The following commonly used relabeling rules must work faster now:
- action: labeldrop
regex: "^foo.+$"
- action: labeldrop
regex: "^bar.*"

lib/storage: ignore start text and end text anchors in getOrValues(regexp) function
...
This is OK, since the anchors are implicitly applied to the whole regexp.
This optimization should improve the speed for regexp series filters with explicit $ and ^ anchors.
For example, `{label="^(foo|bar)$"}`

app/vmstorage: expose vm_{hourly,daily}_series_limit_{max,current}_series metrics if -storage.max{Hourly,Daily}Series limits are set
...
These metrics allow alerting when the number of unique series approach the limit.
For example, the following query alerts when the number of series reaches 90% of the configured limit:
vm_hourly_series_limit_current_series / vm_hourly_series_limit_max_series > 0.9

The ioutil.{Read|Write}File is deprecated since Go1.16 -

VictoriaMetrics needs at least Go1.18, so it is safe to remove ioutil usage
from source code.

* lib/storage: bump max merge concurrency for small parts to 15
The change is based on the feedback from users on github.
Thier examples show, that limit of 8 sometimes become a
bottleneck. Users report that without limit concurrency
can climb up to 15-20 merges at once.

lib/storage: return marshaled metric names from SearchMetricNames
...
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.
While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.
Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series

lib/storage: limit max mergeConcurrency value for systems with high number of CPUs ( #2673 )
...
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.

- 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.
