Base version.py on glance.

This makes setting and calculating the versioning of quantum more
like other OpenStack projects, simplifying the work of the CI
and Release Management teams.

Addresses bug 916018 which prevents the quantum-tarball job from
running correctly.

# This file is placed into the public domain.
# Calculates the current version number. If possible, this is the
# output of “git describe”, modified to conform to the versioning
# scheme that setuptools uses. If “git describe” returns an error
# (most likely because we're in an unpacked copy of a release tarball,
# rather than in a git working copy), then we fall back on reading the
# contents of the RELEASE-VERSION file.
#
# To use this script, simply import it your setup.py file, and use the
# results of get_git_version() as your package version:
#
# from version import *
#
# setup(
# version=get_git_version(),
# .
# .
# .
# )
#
# This will automatically update the RELEASE-VERSION file, if
# necessary. Note that the RELEASE-VERSION file should *not* be
# checked into git; please add it to your top-level .gitignore file.
#
# You'll probably want to distribute the RELEASE-VERSION file in your
# sdist tarballs; to do this, just create a MANIFEST.in file that
# contains the following line:
#
# include RELEASE-VERSION
