Support signal from AbortController to stop container creation

[danilofuchs]

When developing, it is common to start running tests (triggering testcontainers), remembering something and cancelling the run with ctrl+c while the container is still being constructed.

If there was a signal prop, I could hook up SIGTERM to the abort controller and stop the container creation instantly.

In this scenario, if any container is started, it would be automatically cleaned up by the resource reaper. Is it necessary to implement aborting on top?

You are right, I was mistaken and Testcontainers does not hang the process on SIGTERM

ryuk then removes the container, makes sense
