* Update trove from branch 'master'
  - Merge "Add Redis datastore upgrade"
  - Add Redis datastore upgrade
    
    This patch adds support for upgrading Redis datastore - both single
    instance and cluster.
    
    It is achievied in a similar way to MySQL/Mariadb. Steps are:
        + For each node do:
            + stop database
            + preserve configuration files,
            + unmount data volume,
            + create new instance with new datastore,
            + enter restarting mode
            + mount data volume,
            + restore configuration files,
            + reload datastore
    
    Note that due to the Redis Cluster design and Trove approach (all
    nodes are master nodes) we do not perform real rolling upgrade - some
    Redis slots may be unavailable while upgrading node associated with
    them.
    
    This patch adds also a user documentation about upgrading datastores
    using Redis as an example.
