It would be nice to have git bash completion available out of the box

[jachro]

When you create a new project and start an interactive environment it would be nice to have git bash-completion pre-installed already in the image so you can use tab completion for all the git commands. I successfully installed them by adding RUN sudo apt-get install git-core bash-completion --assume-yes to my project's Dockerfile.

Can you make a PR with this to renku-jupyter?
