Create Haskell Development Docker Configuration

[calledtoconstruct]

As a Haskell developer, I want the ability to use an appropriate linux base image, and build a docker image that will include the Haskell compiler, Cabal, Git, and other useful tools, so that I can easily write Haskell applications on any machine capable of using the docker container. Optionally include Nix configuration files such that these tools will be pulled in when accessing the nix-shell.
