Restrict mongodb memory usage
Currently, mongodb has no limits on how much memory it can consume. This enforces restriction so mongodb service limits through systemd. The puppet-systemd module has support for limits. The MemoryLimit support is added in the follwoing pull request https://github.com/camptocamp/puppet-systemd/pull/23 Closes-bug: #1656558 Change-Id: Ie9391aa39532507c5de8dd668a70d5b66e17c891
