Create Docker automated build

[semberal]

We should setup docker automated build for all tags.

Hi @semberal. Dependency on #41 before creating an AB is not ideal.

• With a 'naked' (ie. no drivers built-in) image, people could create their own images with the drivers they need, based on this (official) one. They can even contribute them back, afterwards.
• Licensing mix & match will be slowed down for those like me (IANAL).
• Official Docker image will get visibility sooner.
• Should drivers even be included? Keeping them up-to-date will be an added chore which thord party contrib images can solve.
  So, I would like to ask if you can set up the AB to make the image available to Docker users and leave it open to further contributions adding drivers.

I agree, I removed the dependency.
