Update audit interceptor to set SMF123S1_CLIENT_IP_ADDR to value of X-Forwarded-For when available

Where requests are routed through load balancers and gateways the current SMF123S1_CLIENT_IP_ADDR value does not reflect the true IP address of the client, rather it holds the value of the gateway/load balancer.


We require to know the true value which can be taken from the X-Forwarded-For header when available.

This request is to enhance the audit interceptor to capture the originators ip address to and SMF123 record.
