Bug description:
  ---- Begin SRU Template ----
  [Impact]
  mcollective usage via cloud-init is not possible.

  [Test Case]
  launch instance with cloud-config containing 'mcollective' entry.

  $ cat >user-data <<"EOF"
  #cloud-config
  mcollective:
    conf:
      main_collective: mcollective
      collectives: mcollective
      libdir: /usr/share/mcollective/plugins
      logfile: /var/log/mcollective.log
      loglevel: debug
      daemonize: 1
      direct_addressing: 1
      ttl: 4294957
      securityprovider: psk
      plugin.psk: unset
      identity: 2

      connector: rabbitmq
      plugin.rabbitmq.vhost: mcollective
      plugin.rabbitmq.pool.size: 1
      plugin.rabbitmq.pool.1.host: 10.10.0.2
      plugin.rabbitmq.pool.1.port: 61613
      plugin.rabbitmq.pool.1.user: mcollective
      plugin.rabbitmq.pool.1.password: ScwpVo8egrZ0OmT6sRmp9zEA
      plugin.rabbitmq.heartbeat_interval: 30

      factsource: yaml
      plugin.yaml: /etc/mcollective/facts.yaml
  EOF

  $ keyname=brickies; image=$image;
  $ openstack server create \
     --key-name=$keyname --flavor=m1.small \
     --image=$image --user-data=user-data mcollective-test0

  # then ssh in and
  a.) verify mcollective package is installed
  $ dpkg-query --show mcollective
  mcollective 2.6.0+dfsg-2.1

  b.) verify mcollective service is running
  $ systemctl status mcollective

  c.) grep WARN /var/log/cloud-init.log && echo FAIL

  [Regression Potential]
  low to none.  This has been unfortunately broken since wily.

  [Other Info]
  ---- End SRU Template ----

  How to reproduce:

  #cat /etc/issue.net
  Ubuntu 16.04 LTS
  #( cd /var/lib/cloud/ && rm -rf * )
  #cloud-init -d init

  #grep ^mcollective: -A25 instance/user-data.txt
  mcollective:
    conf:
      main_collective: mcollective
      collectives: mcollective

      ttl: 4294957
      securityprovider: psk
      plugin.psk: unset
      identity: 2

      connector: rabbitmq

      factsource: yaml
      plugin.yaml: /etc/mcollective/facts.yaml

  #cloud-init -d single --name mcollective
