Hi Niels,

This is more complex than I thought, I won't be doing *anything* immediately.
I'll take some time to get configuration right so we don't accidentally end up
in a place where nobody can get work done.

I'm going to slightly change what I originally intended:
1. We will still go ahead with Jenkins Job Builder. It has reasonably good
   documentation, but I'll be available to help in case anyone is stuck. I will
   convert the existing jobs into yaml format for jjb, so they will serve as an
   example. I'll make sure our documentation has a section for how to write
   jobs. Context: JJB was written by Openstack infra team who also use Jenkins
   and Gerrit, so it shouldn't give us too much trouble.
2. The VM restart is an interesting problem that I didn't have insight into
   before. I'm happy to grant current developers access to have access to the
   restart job (We have to define "current developers" at some point).
   Eventually, I hope to make it less of a problem by restarting after every
   X number of jobs, restarting after a failure, or some such (we can talk
   about this later).
3. For release jobs, I'll similiarly create a group who will have full access
   to that job. This way I won't be blocking work while we look at better

Does this solve our immediate concerns?
