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
