This commit is related to elastic#36127. It adds a CcrRestoreSourceService to track Engine.IndexCommitRef need for in-process file restores. When a follower starts restoring a shard through the CcrRepository it opens a session with the leader through the PutCcrRestoreSessionAction. The leader responds to the request by telling the follower what files it needs to fetch for a restore. This is not yet implemented. Once, the restore is complete, the follower closes the session with the DeleteCcrRestoreSessionAction action.
