Create /etc/my.cnf.d/tripleo.cnf with proper bind-address
When fixing LP#1643487 we added ?bind_address to all DB URIs.
Since this clashes with Cellsv2 due to the URIs becoming host
dependent, we need a new approach to pass bind_address to pymysql
that leaves the DB URIs host-independent.
We first create a /etc/my.cnf.d/tripleo.cnf file with a [tripleo]
section and in this section we add the correct bind-address option.
Note that we use the puppet augeas lens and not the mysql one
because the mysql one does not support custom sections *and* there
are older versions around which do not like the /etc/my.cnf.d/* path.
The reason for not reusing an existing mariadb file (my.cnf or
galera.cnf) is that pymysql's ini file support is not robust
enough at the moment: https://github.com/PyMySQL/PyMySQL/issues/548
The reason for putting this file creation code only on the controller
nodes the following: The slow VIP failover only happens if a
service runs where the VIPs exist. The VIPs get created in the
haproxy profile and that is why in order to have fast VIP failovers
the MySQLClient profile must live where the Haproxy service is running.
