Update git submodules

* Update docs/submodules/releng from branch 'master'
  - Apex: Fix slave used by unit test
    
    We were using 'stream' as part of the slave label to run unit tests on.
    However, we typically just use master label for everything to avoid
    having to update labels on slaves.  Changing the unit test to follow the
    same method.
