Description

This isn't that important, but it would be good if we updated the REST API and Web UI to return the instrumentation and configuration for each Oozie server when HA is being used. As it stands, each time you refresh the page (and are going through the load balancer), you'll get the instrumentation/configuration for a different server, which are not identical and there isn't really a way to tell which server they came from. This should be a new version of the REST API (v3) because it would change the return format to be an array of servers with their instrumentation/configuration info.

The backend of this would have the contacted Oozie server simply ask each of the other Oozie servers for their instrumentation or configuration and combine them all (with the name of each server) into the response.
