bad mariadb handling with backup

[tanguyvda]

Hello my friends,

just putting it here before i forget it.

in the centreon-smooth-db-backup we do the following thing

centreon-ha/bin/centreondb-smooth-backup.sh

Line 376 in 9071097

systemctl start mariadb

we shouldn't start mariadb if it is supposed to be handled by a cluster. From what I've seen it will sometimes generates error when the script starts mariadb and we don't want to rely on the mariadb ability to recover from repeated missusage

fix idea:

if [ "$PACEMAKER_ON" = "0" ] ; then
	systemctl start mariadb
fi
