[openstack-dev] [TripleO] Use MariaDB by default on Fedora

I am trying to finish off https://review.openstack.org/#/c/90134 - percona xtradb 
cluster for debian based system.

I have read into this thread that I can error out on Redhat systems when trying to 
install percona and tell them to use mariadb instead, percona isn't support here. Is 
this correct?
