  - [OOF] fix secret names for mariadb-galera
    
    It looks like AAF issues masked my real mistakes of letting
    some of oof services failing because of bad secret names.
    
    Let's fix that quickly by just setting them to the corrent names
    temporarly as later oof will be ported to use common secret template
    anyway.
