Description

The "read-only" mode introduced by SOLR-13721 opens the door to our restoring backup snapshots to already-existing collections.

1. Set read-only mode for the collection in question.
2. Restore a backup to each shard
3. Unset read-only mode for the collection.

See SIP-12 and the corresponding discussion thread for more details.
