lib/promrelabel: optimize matching for commonly used regex patterns in if
option
...
The following regex patterns are optimized:
- literal string match, e.g. "foo"
- prefix match, e.g. "foo.*" and "foo.+"
- substring match, e.g. ".*foo.*" and ".+foo.+"
- alternate values match, e.g. "foo|bar|baz"

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"

- Document the change at docs/CHANGELOG.md
- Move auth token parsing from app/vmagent/opentsdbhttp/ to app/vmagent/main.go,
since it must be parsed only when multitenancy support is enabled at vmagent side.

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

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: improve scalability of blocks processing on systems with multiple CPU cores
...
Previously a single syncwg.WaitGroup was used for tracking the lifetime of processBlock callbacks
across all the per-vmstorage goroutines. This could be slow on systems with many CPU cores
because of inter-CPU synchronization overhead.
Use a separate per-vmstorage sync.WaitGroup instead in order to reduce inter-CPU synchronization overhead.
This should imrpove performance for heavy queries over big number of blocks on multi-CPU systems.
