Add git-crypt support.

[simonjohansson]

I would like to try out concourse, but almost all of my repos are encrypted with git-crypt.

So I was thinking about adding git-crypt support and sending a PR, is this something you are interested in?

I'm not familiar with git-crypt myself, but I'd be happy to look over a PR for adding it.

Only concern I would have is if it's portable enough; we go to great lengths to keep the images for the resources tiny (e.g. based on busybox + buildroot). Looks like it's written in C++, so that may work out OK if you can statically link it or something.

Closing due to inactivity. Still open to the idea but trying to wrangle all our open issues at the moment.

Hey @vito I'm willing to pick this one up, as I need git-crypt for my team. However I'm not super familiar with busybox/buildroot so I don't know how to actually get the git-crypt installed on that image. Any hint?

@vito a co-worker of mine (@dhinus) took a more "drastic" approach and he's adding the git-crypt package to the buildroot distribution (see patch and thread here). This would enable us to tweak concourse/buildroot:git to include git-crypt, does it make sense?

The patch has just landed on master.
