Cache sanitized label names and return them next time.
This reduces the number of allocations and speeds up the SanitizeLabelName()
function for common case when the number of unique label names is smaller than 100k

- alternate values match, e.g. "foo|bar|baz"

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)$"}`

- Properly apply -search.maxPointsSubqueryPerTimeseries limit to subqueries.
Previously the -search.maxPointsPerTimeseries limit was unexpectedly applied to subqueries
if it was smaller than the -search.maxPointsSubqueryPerTimeseries .
- Clarify docs for -search.maxPointsSubqueryPerTimeseries command-line flag .
- Document -search.maxPointsPerTimeseries and -search.maxPointsSubqueryPerTimeseries flags at https://docs.victoriametrics.com/#resource-usage-limits .
- Update docs/CHANGELOG.md .

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.
