Subject: [Bug 1540234] Re: rabbitmq cluster is not work

This patch needs to be reverted as it breaks clusterer on ubuntu. Also,
the behavior you are describing I cannot reproduce and I have a - in my
hostname. The initial config is correct and clusterer should not be
quoted like this, there is another issue at play

====================

Working on ubuntu:

[
  {version, 1},
  {nodes, [
    {rabbit@y-work-laptop01, disc}
  ]},
  {gospel, {node, rabbit@y-work-laptop01}}
].

====================

Broken on ubuntu:

[
  {version, 1},
  {nodes, [
    {'rabbit@y-work-laptop01', disc}
  ]},
  {gospel, {node, 'rabbit@y-work-laptop01'}}
].
