Viewing Source IP using "X-Forwarded-For" headers from API server when using Load Balancer

Issue

• Audit Logs show the load balancer (that sits in front of the master nodes) as SourceIP for all events, however, we would like to see the actual Client IP. This is typically done using X-Forwarded-For headers.

• The sourceIP doc says that it should include IPs from X-Forwarded-For headers in the array, last one being the actual source.
