Deploy MongoDB on scenario002

Some services (like Zaqar) require MongoDB in place to be tested.
We plan to test Zaqar soon, when the Puppet module will be finished.

So this patch is a first iteration by deploying MongoDB.

It also bump the version of puppetlabs-mongodb to use latest release
(0.12).
