Add support for exposing service ports on run

[trvrnrth]

This stems from a need for a step run in a container to have a port exposed that can be connected to from an external testing service whilst it is running.

By default docker compose run does not create the service ports so this adds a configuration to optionally to add the --service-ports option which enables the service ports and maps them to the host.

The default run configuration is not affected.
