Update VID in docker-compose to 4.0-STAGING-latest

Added AAI simulator for new enrichCloudConfigurationWithCloudOwner
feature:
 -  Add AAI response
 -  Update Dockerfile with FROM python, and parametrized config
 -  Add aai-simulator to docker-compose file

BTW, modified SO.py to log to stdio. This enable running `docker logs
so-simulator` to see the rolling output.
