The problem with that is that we would then continue to have to rely on
JClouds to do slave management and we have two driving reasons for this
desire / need to switch to Zuul and Nodepool (or something similar)

1) Recent versions of the Gerrit Trigger plugin for Jenkins forget, or
do not update current triggers on JJB updates without someone either
manually clicking save in the job configuration UI or doing a full
restart of Jenkins. This is a bad thing for us, we're at nearly 2k jobs
managed via JJB many of which are generated by templates and a single
change can affect more than 100 jobs

2) JClouds is a single-threaded nightmare inside Jenkins and can easily
cause it to hang creation of new slaves, deletion of old slaves and
cause the Jenkins queue itself to not start jobs because a single job
got hung and JClouds gets confused. This along with it completely
forgetting about nodes that it started but they failed to connect for
some reason.

So, while that sounds like a viable solution, it's not :(
