Mongodb support

[b0ykoe]

Is your feature request related to a problem? Please describe.
Most serversystems nowdays are using mysql, but more and more tend to shift to mongodb and couchebase since they are documentrelated and are easier to integrate with redis.

Describe the solution you'd like
The solution to safe one service, in this case mysql, would be to add mongodb support. Maybe with morphia that you can just push the class objects into the database.

Describe alternatives you've considered
Well I could use a mysql server but it is an additional service that requires maintenance.
