Speed up git version retrieval by using jgit-describe.jar (Built from https://github.com/ShaneMcC/jgit-describe) to describe the git tag rather than shelling out.
This stops plugin jar building taking 2-5 seconds per plugin by shelling out.
Whilst not a fix exactly for CLIENT-330 - it will make it less of a pressing concern. It would still be nice to fix it though.
