docker-cleanup to garbage collect old images

Docker is a very useful containerisation platform. I use it so much that I regularly fill up /var/lib/docker with old images and get out of disk space errors. Unfortunately Docker has no automatic garbage collection mechanism to clean up unused images. I wrote a simple shell script which I run from time to time.
