Add support for the openSUSE Leap distributions. For openSUSE we use the packages provided by the Open Build Service repository which contains the Galera clustering support. These packages are different compared to the CentOS7 and Ubuntu ones so the way the cluster is being bootstrapped is also different. The systemd service file can't be used for that, so we need to modify the MariaDB configuration file on the boostrap node to initiate the cluster. Moreover, files are installed in different places so we need to modify the distribution files and templates to take that into consideration as well.
