Substring matching for labels doesn't work anymore.
These parts are misleading, and contradict with the rest of the
documentation.

This is an estimate of churn, with series being added to the cache being
considered churn. This will have both false positives (e.g. series
appearing and disappearing) and false negatives (e.g. series hit
sample_limit, but still created in head block), but should be generally
useful as-is.
Relevant docs live in another repo.

I'm willing to do this under the condition that I can run an
experiment with never freezing master. See addition in the file.
I believe, this way is more consistent with how we handle the bugfix
releases after the final minor release is cut. It's at least worth a
try.

1. If alerts is empty after `relabelAlerts`, just return to avoid
subsequent unnecessary operations
2. minor fix in notifier's test case
3. minor fix in comment

* Don't panic if we try to release a string that is not in the interner.
* Move seriesMtx locking in QueueManager's StoreSeries function.
This stops us from calling release for strings that aren't interned if
there's a race between reading a checkpoint and storing new series
labels, which could happen during checkpointing or reloading config.

From the documentation:

This effectively enable keep-alive for the fixed requests.

* Unregister remote write queue manager specific metrics when stopping the
queue manager.
* Use DeleteLabelValues instead of Unregister to remove queue and watcher
related metrics when we stop them. Create those metrics in the structs
start functions rather than in their constructors because of the
ordering of creation, start, and stop in remote storage ApplyConfig.
* Add setMetrics function to WAL watcher so we can set
the watchers metrics in it's Start function, but not
have to call Start in some tests (causes data race).
