Each time we update the proxy from the linkerd2-proxy repo, we make the
change slightly differently. The bin/git-commit-proxy-version does all the
steps needed to update the proxy version up to and including making a
commit to this repo.
The proxy version is now stored in a .proxy-version file and is
consumed directly by Dockerfile-proxy, which both simplifies the
Dockerfile and the update process.
This script formats commit messages and emits output as follows:
