Add Build::GitCheckout to convert the VERSION file to git references.

From the VERSION file, we can determine the branch or tag to we want to build from and then determine a consistent commit_sha for the build.
Use Build::GitCheckout to checkout the right branch and commit sha1.
Clients of this class should only need to read these variables.
Change appliance filename generation to include the git sha1.
