Code review comment for lp:~canonical-platform-qa/ubuntu-system-tests/clean-install

I'm going to see if there's another approach that could work here regarding the imports.

Just to give an idea of the current changes in install size, the trunk branch requires 560MB to install the suite and 452MB to install build-deps.

This branch currently requires 200MB to install suite and 70MB to install build-deps, which is a big reduction.

ubuntu-ui-toolkit-autopilot is 261MB and unity8-autopilot adds another 121MB to that size. So that is why I'm keen to remove them.
