Callum Styan 3639d51eb6 Remote Storage: string interner should not panic in release (#5487) 
* 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.

Callum Styan 1a7923dde3 Add ref counting to string interning so we can remove 
a string when there are no longer any refs. Add tests for interning.
