Authentication interceptor no longer works after nginx upgrade 1.8.1 -> 1.9.0

[anurag-appperfect]

After upgradation of ingress-controller from 1.8.1 -> 1.9.0, interceptor is not working for some of the API's. We verified that nginx is successfully deployed in the kubernetes cluster. We have done some minor changes to nginx.tmpl configuration file:
HttpAccessLogPath: variable renamed to HTTPAccessLogPath
location.Whitelist: variable renamed to location.Allowlist and location.Denylist
EnableRealIp: variable renamed to EnableRealIPafter deployment
