Major Hayden bb1fd16c75 Really fix localhost line in /etc/hosts
This patch ensures that the localhost line in /etc/hosts is
configured properly prior to installing and configuring
RabbitMQ. Without this patch, the RabbitMQ installation often
fails on CentOS 7 since RabbitMQ can't figure out its hostname.

The fix in I6368b6584265084af6ff98caba68fc067b1f1f22 is reverted here
because it had no effect on the /etc/hosts file.
