Open Stack

Just to let you know, there have been requests to run builds/tests on
drafts changes in the past[1] so it seems like there's been mixed
feelings on running CI on changes that are not ready for human review.
  You are correct, making WIP sticky would not work because it is a
per user vote.  If someone (besides the change owner) sets the WIP
vote then the change becomes WIP and the change owner will not be able
to unset the WIP state.  Also to note, the WIP plugin is only
available on version 2.9 so an upgrade would be required.
