Title: [RECOVERY] Allow to cancle recovery sources when shards are closed

Today recovery sources are not cancled if a shard is closed. The recovery target
is already cancled when shards are closed but we should also cleanup and cancel
the sources side since it holds on to shard locks / references until it's closed.
