Bug 1182982

+++ This bug was initially created as a clone of Bug #1147116 +++

Description of problem:
oo-admin-move failed if the network interface eth0 in the node has no ip address.


Version-Release number of selected component (if applicable):
OpenShift Enterprise 2.2
rubygem-openshift-origin-msg-broker-mcollective-1.31.1.1-1.el6op.noarch

How reproducible:
Always on the nodes where eth0 is inactive

Steps to Reproduce:
1. Install OSE with 2 or more node hosts with eth1 as the active interface, or with eth0 being part of a bonded interface.
2. create application 
3. move application using oo-admin-move

Actual results:
Move failed with this error :

DEBUG: Moving content for app '<redacted>', gear '<redacted>' to <redacted>

Additional info:
Ref : 
https://github.com/openshift/origin-server/blob/master/plugins/msg-broker/mcollective/lib/openshift/mcollective_application_container_proxy.rb#L703

The function get_ip_address hard-codes eth0 as the NIC.
