That's definitely good idea.  As you've probably noticed there is a lot of env
variables configured for all slaves.  Is it possible to use the jenkins-jobs
tool to configure those env variables too?  I don't think that's a good idea
configure those env variables directly inside the slaves since they are used
only by Jenkins.
