cloudknot has some Docker issues

Tagging @bloomdt-uw who brought this to my attention

This is a meta-issue concerning cloudknot's use of Docker.

• DockerImage.clobber(), and therefore Knot.clobber(clobber_image=True) seems to remove only the last layer of an image, not the entire thing.
• Knot() instantiation with the same Docker image creates entire new images. The expected behavior is the create new tags of the same image.
• Knot() instantiation is creating containers in addition to images. These containers are still running sometimes after clobber. There is no need to run containers locally so it is mysterious that they are there.

@bloomdt-uw, did I miss anything from our Docker conversation?

Nope. Think this list covers everything.
