Matt Bostock 329a00e44f Relabel: Document whole label set is dropped
From the documentation and current tests, it wasn't immediately clear to
me whether the `target` being dropped as the result of a 'drop' action
was a label key-value pair or the entire labelset.

Add a test that documents this behaviour.

Documentation: https://prometheus.io/docs/operating/configuration/

Julius Volz f63a899744 Change config regexes to full-string matches.
This anchors all regular expressions entered via the config to match a
full string vs. a substring.

THIS IS A BREAKING CHANGE!

Fixes part of https://github.com/prometheus/prometheus/issues/996

Brian Brazil e1d5eb52f2 retrieval: Don't include unmatched source of regex in replacement.
ReplaceAllString only replaces the matching part of the regex,
the unmatched bits around it are left in place. This is not the
expected or desired behaviour as the replacement string should
be everything.

This may break users dependant on this behaviour, but
what they're doing is still possible.

Brian Brazil 4e70a0a14e Retrieval: Add relabel action to map label names with a regex.
The intended use case is where a user has tags/labels coming
from metadata in Kubernetes or EC2, and wants to make
some subset of them into target labels.

Miek Gieben caaa3de4ff Make HashMod use MD5 instead of FNV
MD5 will will distribute the inputs more uniformly over the output
space than FNV; leading to more evenly balanced load when using HashMod.

Brian Brazil 682f949ab1 Add 'hashmod' relabel action.
This takes the modulus of a hash of some labels.
Combined with a keep relabel action, this allows
for sharding of targets across multiple prometheus
servers.

Fabian Reinartz 945c49a2dd Add relabelling to target management.
This commit adds a relabelling stage on the set of base
labels from which a target is created. It allows to drop
targets and rewrite any regular or internal label.
