What are the ping nodes and what are the guidelines in a Genesis ZX Metro cluster or cluster setup?

Ping nodes are 2 stable IP addresses on the "ring" subnet of Genesis ZX metro cluster or cluster.  They are used in failover operations for both nodes to get a sense of the health of each others ring node networks and are used for both nodes to determine the most healthy node to avoid split brains.  


Set the 2 IPs based on something very stable in the network, like a Switch IP Management address, a Gateway Address, a router address, or a DNS etc.  Something that is very unlikely to be unreachable in the site.
