Add way to backup from MariaDB replica server
ProxySQL reports its version to MySQL clients,
causing the backup process to fail when ProxySQL is used.
This patch adds a new script that handles backups from
the replica server directly, without modifying the original
backup script. The new script retrieves the server address
via the load balancer and connects directly to the replica
server to execute the backup.
Moreover, this reduces the risk that the backup will be inconsistent
or that it will block OpenStack MySQL clients, because they are
connected to a different server, and no one is connected to the replica,
or that it will overload the load balancer (such as ProxySQL or HAProxy)
which listens on the VIP.
