lib/promscrape: implement target-level and metric-level relabel debugging
...
Target-level debugging is performed by clicking the 'debug' link at the corresponding target
on either http://vmagent:8429/targets page or on http://vmagent:8428/service-discovery page.
Metric-level debugging is perfromed at http://vmagent:8429/metric-relabel-debug page.

lib/promrelabel: remove unconditional sorting of the labels in ParsedConfigs.Apply(), since the sorting isnt needed in many places
...
Sort labels explicitly after calling the ParsedConfigs.Apply() when needed.
This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.

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/promrelabel: optimize action: {labeldrop,labelkeep,keep,drop} with regex containing alternate values
...
For example, the following relabeling rule must work much faster now:
- action: labeldrop
regex: "foo|bar|baz"
