Stop to require MongoDB validation (this provider requies MongoDB working on the same node) so we can install MongoDB nodes outside Telemetry Collector service. This patch is a workaround until: https://github.com/puppetlabs/puppetlabs-mongodb/pull/200 is merged so we can use the code in this module. See https://review.openstack.org/179824 Change-Id: I80b102c3801efea262e6572fce1f64eb8a9a67ad
