Support One-Shot Containers in `docker-compose`

[ControlCplusControlV]

Right now when using docker compose I have one-shot containers which I use for postgres container settings / patches, but this causes docker compose to break with testcontainers-rs I believe mostly because --wait will always timeout

I think the best way to do this is to allow --detach if possible, I'm happy to implement this if you want, but ideally I'd like to just detach with a sleep rather than using --wait since the one shot containers need to startup, run, then die
