customizing mariadb role

Hi there,

I would like to customize some values that are stored in
roles/mariadb/templates/50-server.cnf.j2

From what I can see, some values can be but not all of them like max_allowed_packet.
There are several ways to do it but I am wondering what would be the best way in order to keep trellis logic.

I also would like to add some values related to mysql replication.

Regards

The good way is to turn it into an ansible variable.
The best way is to do that in a roots/trellis pull request.
