galera_server is using repo by default instead of packages in centos

[Jean-Philippe Evrard]

With ubuntu use_percona_upstream is set to no, while in centos it's set to yes.

We should be consistent, and fix centos.

[Marc Gariépy (mgariepy)]

So the consistency would be to install mariadb from RDO packages instead of upstream.

[Markos Chandras (hwoarang)]

It does not seem the RDO (at least for Pike) provides galera packages.

    tasks: Fix use_percona_upstream variable usage

    The 'use_percona_upstream' variable had quite different and conflicting
    meanings in the tasks. It's used to either denote that the upstream
    packages will be used directly or that the upstream repositories will
    be configured on the hosts and then use the packages from these
    repositories. However, the packages in both cases are the same so the
    variable was pointless in this form. The variable was meant to be used
    to select between upstream and downstream repositories for the Percona
    packages. Moreover, upstream does not provide packages for SUSE so we
    have to exit the deployment if that variable is set.

    Partial-Bug: #1654004
