Lmod / module support

[rkdarst]

I just added Lmod support and an example hello modulefile, that adds in hello-world script that does the obvious.

While this isn't exactly Slurm, I guess many Slurm setups use this, so would you be interested in taking it upstream?

It is findable here: https://github.com/AaltoSciComp/docker-centos7-slurm/ (on master currently, no direct link to the commit since I am likely to rebase)

This looks good! What if we were to put contributions like this in a contrib folder in the project, and place shell scripts there that adds functionality, like adding Lmod support?

That way, once a user uses the container, they can easily add things by executing the scripts, while other users can, by default, choose not to include it if not needed.

Thoughts?
