Update git submodules

* Update docs/submodules/apex from branch 'master'
  - Remove deploy.sh and references

    Deploy is now pip/rpm installed as opnfv-deploy in /bin.  Alternatively
    the deploy.py script can be invoked via python.  The legacy deploy.sh
    was only being used for CI, which has now been updated to remove the
    need for the Apex repo containing ci/deploy.sh.
