org.elasticsearch.indices.recovery.RecoveryTarget#restoreFileFromSnapshot does not check for cancellation during the download of a file. This means that if a recovery is cancelled mid-way, we will still not release the store/shard-lock until the file is fully downloaded.
For large files or slow downloads this can lead to problems when the shard is (re-)allocated to a node that is still executing such an interrupted recovery.

-> we need to add some checks for cancellation here like we have for other recovery modes.
