endpointslices roles.

We always track total samples queried and add those to the standard set
of stats queries can report.
We also allow optionally tracking per-step samples queried. This must be
enabled both at the engine and query level to be tracked and rendered.
The engine flag is exposed via a Prometheus feature flag, while the
query flag is set when stats=all.

clear that it acts on all the label names, rather than the list provided
by source_labels.

* Allow escaping a dollar sign when expanding external labels
There is currently no mechanism to natively escape a dollar sign
in the os.Expand function. As a workaround, this commit modifies
the external label expansion logic to treat a double dollar ($$)
as a mechanism for escaping the dollar character.

Split out the note about regex-matching into a separate paragraph to
make it more obvious. Move it up, closer to the definition.
