Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Apex: add support for deploying upstream only

    Scenario names with 'upstream' in them will not download any artifacts
    and deploy from upstream.  For now, this even applies to the apex
    python RPM for daily deployments.  We will only use git repo for
    daily until after Fraser.
