Add general_log to mariadb container and make heka collect it

[Vikram Hosakote]

mariadb needs two types of logging enabled in ansible/roles/mariadb/templates/galera.cnf.j2.

1) "log-error" that logs just the mariadb errors (https://github.com/openstack/kolla/blob/master/ansible/roles/mariadb/templates/galera.cnf.j2#L6)

2) "general_log" that logs all the other mariadb activities and database queries. general_log is not in ansible/roles/mariadb/templates/galera.cnf.j2.

general_log must also be added to ansible/roles/mariadb/templates/galera.cnf.j2 so that all the mariadb logs are seen. This will be helpful to debug mariadb issues especially when mariadb is scaled.

Change abandoned by Vikram Hosakote (<email address hidden>) on branch: stable/mitaka
Review: https://review.openstack.org/301975
Reason: Abandoning this patch set as general_log is too verbose and consumes a lot of disk space. This change will be reverted in master as well.

[Steven Dake (sdake)]

Removing from Mitaka since this will be reverted in master.
