Support for relational databases

[lhrinaldi]

First of all, great generator! Really fond of the structure and how it separates some concerns.
I'm thinking of always adopting this structure for my future APIs, but sometimes I need to use a relational database like Postgres. I managed to remove mongo and integrate objection.js and Postgres inside the same structure, could be a way to start.

Anyway, my question is, are there any plans to support relational databases? Maybe in a different branch?
I can work on a PR for this integration but first needed to know if it'd be useful.

This would be great +1

I would love to see a mySQL integration! :)
