Description of problem:
When running packstack on RHEL 7.1 on a host with a hostname of 64 bytes in length RabbitMQ fails to start 

Version-Release number of selected component (if applicable):
Packstack version-
packstack Kilo 2015.1.dev1537.gba5183c
uname -
Linux rdo-testday-ipv6-rhel-7.1-38593203-90d9-4755-882d-e52c72076ea5.n 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38 EST 2015 x86_64 x86_64 x86_64 GNU/Linux
RHEL version -
Red Hat Enterprise Linux Server release 7.1 (Maipo)
amqp version -
python-amqp-1.4.6-1.el7.noarch

How reproducible:
Run packstack on a 64 bytes length hostname machine

Steps to Reproduce:
1. Configure your host's hostname to a 64 bytes length
2. Install packstack: yum install openstack-packstack
3. Generate answer file and edit as needed: packstack --gen-answer-file=<name>
4. Run installation: packstack --answer-file=<name>

Actual results:
Installation fails when trying to start RabbitMQ service

Expected results:
Installation finished successfully
