While on the topic of reducing the CI footprint

something worth considering when pushing up a string of patches would
be to remove a bunch of the check jobs at the start of the patch set.

e.g. If I'm working on t-h-t and have a series of 10 patches, while
looking for feedback I could remove most of the jobs from
zuul.d/layout.yaml in patch 1 so all 10 patches don't run the entire
suite of CI jobs. Once it becomes clear that the patchset is nearly
ready to merge, I change patch 1 leave zuul.d/layout.yaml as is.

I'm not suggesting everybody does this but anybody who tends to push
up multiple patch sets together could consider it to not tie up
resources for hours.
