Raphael S. Carvalho 707ebf9cf7 replica: Make move_sstables_from_staging() robust and compaction group friendly

Off-strategy can happen in parallel to view building.

A semaphore is used to ensure they don't step on each other's
toe.

If off-strategy completes first, then move_sstables_from_staging()
won't find the SSTable alive and won't reach code to add
the file to the backlog tracker.

If view building completes first, the SSTable exists, but it's
not reshaped yet (has repair origin) and shouldn't be
added to the backlog tracker.

Off-strategy completion code will make sure new sstables added
to main set are accounted by the backlog tracker, so
move_sstables_from_staging() only need to add to tracker files
which are certainly not going through a reshape compaction.

So let's take these facts into account to make the procedure
more robust and compaction group friendly. Very welcome change
for when multiple groups are supported.
