[Linux-cluster] Higher Grained Definition of IP AddressAssignments

[Dustin Henry Offutt]

I've spent the past year architecting an HA cluster with RHCS and it's 
working wonderfully. I have not seen anything superior.

Due to a new customer-driven feature of our software, we need to add the 
ability for a cluster service/resource group to have up to eight 
distinct IPs on one particular network due to the software being made 
highly available via RHCS performing its own load balancing. Placing the 
load balancing elsewhere is not an option due to the nature of the product.

Regarding "OCF_RESKEY_," will google more on this and appreciate the 
tip. Must work this out some way.
