The idea is to stop changing mcollective config and restarting it from
nailgun agent. This causes a lot of problems related to mcollective
config restarted at wrong time. From now at the bootstrap stage
mcollective is expected to be configured and started by startup scripts
while in bootstrap and by cloud-init at first boot into provisioned
node.
