SUSE: Switch to upstream MariaDB repository

The OBS development repository was proven to be quite fragile since
the mariadb packages were moving far to quickly. Whilst this has helped
to catch bugs when OpenStack services were used against newer MariaDB
versions, it also created a very unstable infrastructure for openSUSE
deployments. As such, we have now switched to using the upstream SLE
packages as provided by MariaDB upstream so all distributions are
aligned to how they deploy the Galera clusters. This further allow us
to report upstream bugs which fix problems across all distributions.
