Remove MongoDB

MongoDB hasn't been supported since Pike, it's time to remove the
deployment files. Starting in Stein, it's not possible to deploy MongoDB
anymore. It already changes the default zaqar management_store to
sqlalchemy and the zaqar messaging_store to redis, which is already
set by TripleO Heat Templates.
