Michal Arbet 8f0a4bcb0d Switch mariadb's loadbalancer from HAProxy to ProxySQL
It's been some time since ProxySQL has been
with us in Kolla. Let's switch the load balancer
for MariaDB connections from HAProxy to ProxySQL.

The config option ``enable_proxysql`` has been changed to
``yes``, which means that MySQL connections will now be
handled by ProxySQL by default instead of HAProxy. Users
who wish to retain load balancing of MySQL connections
through HAProxy must set ``enable_proxysql`` to ``no``.
Also Due to this change, the config option
``enable_mariadb_clustercheck`` is also dynamically
changed to ``no``. Users who still wish to maintain
``mariadb_clustercheck`` can override this config option
in the configuration. However, with ProxySQL,
``mariadb_clustercheck`` is no longer needed and can be
manually removed.
