    tidy stx/downloads directory

    $MY_REPO/stx/downloads contains links to tarballs and other files
    relevant to the build. It is populated by populate_downloads.sh.
    On subsequent runs, new links might be added, but old links are
    not cleaned up.

    Adopt the convention used by generate-centos-repo.sh of moving
    the old content under a timestamp backup directory, leaving
    an empty directory to re-populate.

    Improved branching tools

    create_branches_and_tags.sh:
    - Update the .gitreview files in branched git repos.
    - When updating a manifest, add the ability to update and
      use the default revision field.
    - Create two levels of manifest lockdown, soft and hard.
      Soft lockdown only sets sha revisions on unbranched projects
      that lack a revision, or set the revision to master.
      Hard lockdown applies to all unbranched projects.

    push_branches_tags.sh:
    - opendev no longer accepts 'git push' for the delivery of
      new branches with updates. Instead we must now
      use separate commands to deliver the tag, the branch,
      and any updates.

    Fix wheels tarball generation

    In d7c5a54ab94bce6635b83d91a807d28f97836a81, django was dropped in favor
    of rfc3986. However the wheel was not added to the build-wheels
    generation which breaks the docker images. Also add the migrate wheel
    since it was mising as well. Add the required wheels in order to
    build the docker image properly.

    Test:
    - Build new centos-stable-wheels tarball
    - Build stx-keystone-api-proxy container

    fix bad flockflock url pt 2

    A stray '}' character found it's way into my prior update
    titled 'fix bad flockflock url' after testing. The result was
    the following error

    sed: -e expression #1, char 15: unexpected `}'

    This removes the unwanted '}', restoring the prior update
    to its intended form.

    fix git-review within docker build environment

    'tb create' fails to create a build environment since
    upstream git-review was updated of Apr 26.

    Fix is to install/update pbr ahead of git-review.

    Also, to reduce the likelyhood of this recurring, lock
    down specific versions of the pypi supplied tools we
    know to work.

    fix bad flockflock url

    download_mirror.sh fails due to a bad path containing
    ‘stx-tools/centos-mirror-tools/config/centos/flockflock’

    The path is constructed, and the trigger is when an EOL is missing
    from a centos_build_layer.cfg file, causing 'cat' to merge the last
    line of the offending file with the first line of the next file.

    Switch 'cat' to 'grep', which will always ensure an EOL is present.
    Along the way, we can filter out empty lines and comments.
