How to update the address/IP of an existing node

[travisshivers]

How would I go about updating the ip or address of an existing node if it changed for whatever reason, such as if the pod got killed or restarted with a new version?

If the node is a master node, I can't delete and add it again as the API won't allow deleting the master node.

@travisshivers We need to add a new node as a replica and fail over the master to the new node, then we can delete the old master node.
