    Migrate to pbr for build

    pbr is the libification of what was openstack.common.setup. If provides
    the build information in a delcarative form, instead of as executable python
    code, which works around the chicken and egg problem of needing setup
    libraries present to run setup, but needing to run setup to tell if you
    need setup libraries.

    One of the features that comes along with this is versioning based on
    git tags. If the current revision is a signed git tag, then that is the
    version of the package. If it is not, the version is equal to the most
    recent git tag, plus a commit count, plus a git sha (similar to git
    describe, but scrubbed for python version rules compliance)

    pbr updates are also part of the upcoming automation around ensuring
    global requirements stay in sync.
