Add basic dockerfile

[colemickens]

This will at least let users get up and running without needing to worry about dependencies, or let them run on non 14.04 systems.

It'd be better if in the future the build output a versioned docker container - it might look very similar to this Dockerfile but the tarball would be ADDed instead of how this installs wget and pulls down whatever happens to be the latest version.

If there are build instructions for Linux I can take a crack at it.

How do I prompt the bot to rebuild this? This shouldn't impact any existing tests.

Just curios why don't you just RUN apt-get -qqy update && apt-get -qqy upgrade && etc.

[colemickens]

Are you asking about the use of ; vs && ? You're right, it would be best to use &&. I'll update momentarily.

@colemickens Thanks for the contribution! Please respond to feedback

Pushed a new commit based on one of the pieces of feedback. Just rebuilt the container to check -- az is available and executable as soon as the container starts.
