Update git submodules

* Update docs/submodules/aai/event-client.git from branch 'master'
  to a380de15aca76818368f4cd6a33b1a5252420e79
  - Migrate aai-event-client docs

    Merging this will create
    https://onap-aai-event-client.readthedocs.io
    This build will run in parallel
    to the current docs generation method
    until we are ready to cut over.
