refactor(docker): directus use postgress, redis and fix cors (#26)

* directus use postgress, redis and fix cors

In order to use gis features you can install some plugins to sqlite or
use postgres which supports those features natively.
Use a redis cache as this was part of the advanced setup example.
Furthermore fix cors and allow http://localhost:8080 by default.

* lint fixes
