[ClusterLabs] Passing and binding to virtual IP in my service

[Nikhil Utane]

What I had posted earlier was an approach to do N+1 Redundancy for my
use-case (which could be different from yours).
Attaching the same and the cib xml to this thread (Don't know if
attachments are allowed.)
There are some follow-up questions that I am posting on my other thread.
Please check that.
