Updated git submodules

Project: sdnc/oam master a8ebccfdd2fd1ebf51148b95f6a673ba58f38290

Remove nexus URL from docker-compose.yml

Integration scripts expect to pull docker image locally, with local tag
'latest' - so nexus URL should not be in image name.  Leaving it
in ueblistener since that docker container is not yet in integration
startup script (so no local tag created).
