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: increase the maximum possible or values extracted from regexp from 20 to 100

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)$"}`

- Document -search.maxPointsPerTimeseries and -search.maxPointsSubqueryPerTimeseries flags at https://docs.victoriametrics.com/#resource-usage-limits .
- Update docs/CHANGELOG.md .

We switch default alert's source link to redirect user

compatibility, it also supposed to improve user's experience.
The old behavior can be achieved by updating `-external.alert.source`
command-line flag.
