[Feature Request] Ability to "Kill" container

[jeffijoe]

Loving this library, fantastic work!

I was wondering if it would be possible to introduce a .Kill() on IContainerService that would use docker kill?

When tearing down an integration test, we usually don't want to wait for the container to gracefully exit, since they are disposable anyway. Some images like Google's PubSub emulator in the image gcr.io/google.com/cloudsdktool/cloud-sdk:emulators seems to ignore the SIGTERM and so it'll take an extra 10 seconds for .Stop() to finish.

This is an excellent idea! I'll add it to my todo list!

Cheers,
