Well, the plugin that barak passed before, the one that forces a slave
to be used only once, is what openstack guys use, in combination with
nodepool, a big python service to provision/manage slaves, that's what
I wanted to avoid, that extra service (as a jenkins job or not) to
exclusively handle slaves, when we already have the ovirt pool stuff
