The galera_server and galera_client roles both configure the apt or
yum repository for galera and percona. This can cause a conflict if
the version of the client and server differ.
This patch sets the galera_client dependency to deploy the /root/.my.cnf
file rather than installing all the client packages as well. The client
package is already deployed as part of the galera_server role
deployment.
