Fix docker compose to make it running with older docker images

[varmar05]

After split of celery-* and server containers running docker-compose.yml with CE/EE older images results in confusing situation, e.g. running services multiple times or not running them all. This is because we changed entrypoint.sh to accept any runtime command from docker-compose file which is not respected by older images.

To overcome this limitation new entrypoint.sh is mounted to replace the one built in images.
Also missing keys were added for celery containers in compose file.
