User IP is not available in apim_metrics.log in failure scenarios

[vinok88]

Description

The API manager is configured to use ELK analytics. When a request fails due to a reason such as authentication failure, we do not log the user IP (X-forwarded header). But in success scenarios, this header is printed.
Include the user IP in failure scenarios as well.

Steps to Reproduce

Enable ELK analytics in deployment.toml
Enable additional logs as per the documentation.
Check the apim_metrics.log for a success and failed scenario
