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/promrelabel: optimize action: {labeldrop,labelkeep,keep,drop} with regex containing alternate values
For example, the following relabeling rule must work much faster now:

- action: labeldrop
  regex: "foo|bar|baz"

lib/storage: increase the maximum possible or values extracted from regexp from 20 to 100
This should improve time series search speed for regexp filters with big number of `or` values.

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

lib/storage: bump max merge concurrency for small parts to 15 (#2997)
* 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.

vmalert: set alert's source link to UI instead of JSON source (#2986)
We switch default alert's source link to redirect user
to vmalert's UI instead of previous JSON object. While it breaks
compatibility, it also supposed to improve user's experience.
The old behavior can be achieved by updating `-external.alert.source`
command-line flag.

app/vmselect/netstorage: fix a bug introduced in 1a254ea20c
The bug results in `duplicate output time series` error
because the same time series is added two times into the orderedMetricNames list
inside the tmpBlocksFileWrapper.Finalize().

While at it, properly release all the tmpBlocksFile structs on tbf.Finalize() error.
Previously only the remaining tbf entries were released. This could result in resource leak.
