Proper database support

[Perflyst]

I know you are currently waiting of moigagoo/norm#19 but this adds MongoDB which is probably not the best database for this kind of caching.

Why not just using PostgreSQL? If MongoDB is just for caching than okay, this will work fine. But if you add user account and following support (maybe also liking etc) I do not think MongoDB is the correct choice.

Can you elaborate on why you don't think it's a good choice? The main reason I want to use MongoDB is how easy it's going to be thanks to the norm PR. PostgreSQL support isn't nearly as good (regarding storage of objects, lists, optional types, etc).

If MongoDB grows up in size it will be noticeable slower. Also restart takes much longer.
Of coure if it is easier for you and if Postgres is not supported that well for the data you will store in it than use Mongo.

Redis is now used which is a blazing fast in-memory multi-model database, suitable for everything nitter could ever want to store
