Whatever the outcome of bug 1565332, one thing is true; Debian 10 and Ubuntu 18.04 both could be somewhat larger than the existing Ubuntu 16.04 docker image.

For example:
Ubuntu 18.04: 1264.467 mb
Debian 10: 1392.757 mb
Ubuntu 16.04: ~900 mb

Now, since Ubuntu 16.04 is the default image on CI, it is often cached so does not need to be downloaded then loaded into docker. 

Even then, I suspect we can do better than the 1.2GB size of the newer images. 

In this bug, aim for the following:

- reduce the size of the docker image, with overachieve goal being 50%
- eliminate as many support and configuration files as possible
- reduce the number of steps in the setup phase
- reduce the time taken to build, with overachieve goal being somewhere in the mid-20min mark
