openstacklib::db::mysql['nova_cell0'] has no dependency on openstacklib::db::mysql['nova']

[Martin Schuppert]

If openstacklib::db::mysql['nova_cell0'] runs before openstacklib::db::mysql['nova'], as there is no dependency [1], we fail to grant privileges as nova_cell0 is executed with "create_user => false".
