commit 674bd8c62a84fc62b3731355d66a8d5596ff61d9
Author: Jeremy Stanley <fungi@yuggoth.org>

    Update git submodules
    
    * Update pbr from branch 'master'
      - Run tempest-full for stable/train
    
        The tempest-full job runs Python 2.7 (as opposed to
        tempest-full-py3) so will want to install Python library packages
        which have been dropped in Focal in favor of their python3-.*
        replacements. Switch this job to use stable/train branches of
        required projects as they still expected 2.7 to work, and as a side
        effect this will cause the appropriate nodeset to be chosen
        automatically.
