lib/promscrape: optimize discoveryutils.SanitizeLabelName()
...
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

The following regex patterns are optimized:

- substring match, e.g. ".*foo.*" and ".+foo.+"
- 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)$"}`

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