Garbage collect asynchronously in the WAL Watcher 
The WAL Watcher replays a checkpoint after it is created in order to
garbage collect series that no longer exist in the WAL. Currently the
garbage collection process is done serially with reading from the tip of
the WAL which can cause large delays in writing samples to remote
storage just after compaction occurs.

This also fixes a memory leak where dropped series are not cleaned up as
part of the SeriesReset process.

Lucas Servén Marín 8ab628b354 tsdb: allow readonly DB to create flush WAL (#6006) 
This PR gives the readonly DB the ability to create blocks from the WAL.
In order to implement this, we modify DBReadOnly.Blocks() to return an
empty slice and no error if no blocks are found.
