lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added
metric
...
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.
The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

lib/promrelabel: add keep_metrics
and drop_metrics
actions to relabeling rules
...
These actions simlify metrics filtering. For example,
- action: keep_metrics
regex: 'foo|bar|baz'
would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted.
The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above:
- action: keep_metrics
regex:
- foo
- bar
- baz
