    Allow a log dir that isn't the "service_name"

    Galera logs by default to /var/log/mysql_logs these logs are being
    ignored and not mounted properly on the host server, because the
    service_name that is used to mount the log directory is "galera" and not
    "mysql_logs".

    This patch adds an option to set the log_directory specifically inside
    the env.d yml files, but defaults to "service_name" when the
    log_directory option isn't set. This will mean functionality remains
    unchanged for all services.

    Additionally, the log_directory has changed to "mysql_logs" for galera
    containers, to resolve the galera log issue.
