Docker db decouple

[matthdsm]

Hi,

I made some effort to decouple the db from the existing docker image.
I've also simplified the docker image and swapped out the base image, which should yield some perfomance bumps.

As far as I can see, everything seems to work, but I suppose some further testing is required.
TODO's

• create script for SQLalchemy migrations using alembic on startup

Cheers

Some other feedback:

• We should add a docker-compose file that includes a Postgres database, so that users can run the entire stack automatically
• There should be a test in travis for the Docker image. Something simple like building it and then running it should be enough

Same here

Agreed, this is something I was thinking about too

• There should be a test in travis for the Docker image. Something simple like building it and then running it should be enough

Also agreed

Many thanks for this @matthdsm! The Dockerfile is much much cleaner.. 👍 Nice work!
