This seems like a good fix to make "quick links" work out of the box when the cluster is deployed
on GCE.
However, as mentioned in the corresponding JIRA, this patch has a side effect of showing IP
addresses, rather than hostnames, in the Hosts page and Host Detail page in Ambari Web UI.
 This is a result of these pages using public hostnames rather than internal hostnames as
they should.
We ideally change the Hosts and Host Detail pages to show internal hostname instead, but this
is sort of a big UI change for those who are used to the current behavior and would be a surprise.
 
This level of change in the UI behavior is justified for the 2.0 release, so I say hold off
on committing this until the 1.7.0 branch is cut (and we'll commit the accompanying UI changes
together).  
Thoughts?

difference is that at GCC there is no public hostname only public IP. We could use this IP
as the public hostname as the hosts are not reachable any other way outside the VPC.
