[puppet] How to disable installation of mysql::server and only create databases?

Hey openstack-discuss, is there any intended way of using e.g cinder::db::mysql (which is using puppet-openstacklib) to create databases, but not also run / include mysql::server which apparently happens at https://github.com/openstack/puppet-openstacklib/blob/33fb90326fadd59759d4a6... ? In short I already have a running database server and only want the databases to be created. Thanks, Christian
