An explicit part of this plan is that all of the things you're talking
about are *not* in scope until the forklift is complete and the new
thing is a functional replacement for the existing nova-scheduler.  We
want to get the project established and going so that it is a place
where this work can take place.  We do *not* want to slow down the work
of getting the project established by making these things a prerequisite.
