There is no reason not to allow deletes in parallel to restores if they're dealing with different snapshots. A delete will not remove any files related to the snapshot that is being restored if it is different from the deleted snapshot because those files will still be referenced by the restoring snapshot. Loading RepositoryData concurrently to modifying it is concurrency safe nowadays as well since the repo generation is tracked in the cluster state. Closes elastic#41463
