Each slave in a mysql replication cluster needs to have a unique 'server-id' set. This is an arbitrary integer, and often people select 1,2,3 etc. For easy deterministic uniqueness without needing to look at what you've already used, a simple filter has been created to allow for the hostname to be converted into an integer. The server ID variable has been added to the my.cnf.j2 template and the galera_server defaults/main.yml file. The generation of the server-id variable happens within the `galera-install.yml` play making it so there is no future impact in role requires.
