[FEATURE] - Custom postgres port and DB name

[dani]

Is your feature request related to a problem? Please describe.
Maybe I overlooked something, but I couldn't find how to specify a custom port for the postgres server. Nor the DB name. The docker-compose file only mention user, password and host

Describe the solution you'd like
In my environment (I intend to run controlR on Nomad) I need to use a custom port to reach postgres. I also need to control the DB name the app will use.

Describe alternatives you've considered

This is my first time learning about Nomad. Interesting! I'll have to read up more on it.

I'll add options for changing DB name and port in the next release.
