Update git submodules

* Update docs/submodules/apex from branch 'master'
  - Adds the ability to fetch logs from deployment

    Usage:
    opnfv-pyutil --fetch-logs
    python3 utils.py --fetch-logs --lib-dir ../lib

    Eventually all utils.sh functions will be migrated here.
    Note there is no support here for containers.  Will be
    added later.
