Update git submodules

* Update docs/submodules/apex from branch 'master'
  - Merge "Fixes ensuring VBMCs are actually running"
  - Fixes ensuring VBMCs are actually running

    We currently start VBMCs using CLI due to issues with the VBMC python
    lib.  However when we start them, there is no check to make sure they
    are actually changed to 'running' status.  This patch adds logic to
    check (up to 5 times) to ensure each VBMC is running or raises an error.
    Note this is for virtual deployments only.
