    Decrease MariaDB wait timeout

    This MariaDB setting uses the same timeout for SQL connections
    as configured inside SQL Alchemy (pool_recycle) and prevent possibly
    SQL session build up due to a large default setting (8 Hours).

    Nova and Neutron are using a idle_timeout of 3600 by default,
    for example
    https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L101
    and respectively for Neutron
    https://github.com/openstack/neutron/blob/stable/liberty/etc/neutron.conf#L761
