DockerCompose: wait logic inspect yaml

[rukai]

Change the DockerCompose's wait logic to:

1. parse the docker-compose.yaml to find what images each service uses.
2. consult a hardcoded list that associates images with a required log substring.
3. wait until each service's log contains the required string for the image it uses.

This new implementation is more robust:

• We can now increase the number of services in a docker-compose.yaml without it silently introducing intermittent failures.
• Its also more convenient as we can create or move docker-compose.yamls without having to alter the hardcoded list.

However my main motivation was actually to allow restarting of docker-compose instances that have been stopped.
Without this rewrite it would be impossible to wait on a single service to start as we currently rely on a hardcoded number of services.
