Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Merge "Create branches via ssh rather than the https"
  - Create branches via ssh rather than the https
    
    Previously we created the branches over Gerrit's HTTPS interface. One or
    two projects from the previous release did not have their stable
    branches created at the correct place.
    
    Switch to using ssh for branch creation will be more reliable and easier
    for us to verify.
