Description of problem:

When I installed all rdo packages in single command I noticed the following warning.

 Installing : openstack-neutron-openvswitch-2014.1-0.10.b3.fc21.noar   243/325
 warning: group neutron does not exist - using root

I also noticed the service was not able to start because of the wrong permissions of 
/etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini

Version-Release number of selected component (if applicable):
openstack-neutron-openvswitch-2014.1-0.10.b3.fc21.noarch

How reproducible:
always

Steps to Reproduce:
1. yum install -y openstack-neutron-openvswitch # before any other neutron package
2. ls -l /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini
-rw-r-----. 1 root root 6149 Mar  6 16:38 /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini

3.$ service neutron-openvswitch-agent start

Actual results:
Redirecting to /bin/systemctl status  neutron-openvswitch-agent.service

Expected results:
 - The service is able to read the sample config file.
 - I should not get a warning message on installation.

Additional info:
 $ getent passwd neutron
neutron:x:999:998:OpenStack Neutron Daemons:/var/lib/neutron:/sbin/nologin
 $ getent group neutron
neutron:x:998:

neutron user and group was created during the installation.

I wonder isn't the neutron-openvswitch-agent should use the /etc/neutron/plugin.ini symbolic link as default config file, 
and as the user I need to create the correct symbolic link as described here: http://openstack.redhat.com/ML2_plugin
