Get RPM and Kuryr version from git

This commit makes sure we're getting the version to use as RPM and
Python package semver from the last tag in git. This should solve issue
of `kuryr-k8s-controller --version` returning 0.0.0 and remove the need
to update versions in various places each time master gets opened to new
release development.
