[DIB] mysql element: mariadb-server is not always installed on RHEL7

[Luigi Toscano]

Depending on the available subscriptions, 'yum install mysql-server' does not always install mariadb-server (the default version on RHEL7). The mapping for CentOS7 already specify the proper name for the packages, so the mapping for RHEL7 should be added as well.

Even if the server is installed at runtime (for example by MapR), preloading saves a bit of time (and it works already for CentOS7).

This is a candidate for a backport to Ocata and possibly to Newton.
