Description

We should have an easy way to do backups and restores in SolrCloud. The ReplicationHandler supports a backup command which can create snapshots of the index but that is too little.

The command should be able to backup:

1. Snapshots of all indexes or indexes from the leader or the shards
2. Config set
3. Cluster state
4. Cluster properties
5. Aliases
6. Overseer work queue?

A restore should be able to completely restore the cloud i.e. no manual steps required other than bringing nodes back up or setting up a new cloud cluster.

SOLR-5340 will be a part of this issue.
