4aeb8db83f lib/promscrape: add ability to set series_limit and stream_parse options via relabeling
This allows managing these options on a per-target basis.

Typical use case: to manage these options for pods via Kubernetes annotations.

d6bd956930 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

d5622b32e2 lib/promscrape: reduce memory and CPU usage when Prometheus staleness tracking is enabled for metrics from deleted / disappeared scrape targets
Store the scraped response body instead of storing the parsed and relabeld metrics.
This should reduce memory usage, since the response body takes less memory than the parsed and relabeled metrics.
This is especially true for Kubernetes service discovery, which adds many long labels for all the scraped metrics.

This should also reduce CPU usage, since the marshaling of the parsed
and relabeld metrics has been substituted by response body copying.
