Cleanup Docker containers or container name cache

[BradCrumb]

I'am using the plugin for a couple of weeks now with Docker. I noticed that every time a new container will be started the old ones are still available but never been used again.

I think there are 2 options to optimize this:

Option 1: Add --rm to the docker run command. When a container has been used and exited it will be automatically removed and it will keep your list of containers clean.

Option 2: When a container has been initialized, keep the container name in cache and re-use the container the next time it needs to be started. Maybe this can be linked to the PHP project.

Option 1 sounds like a quick-and-easy solution to this. I'll add it.
