Configuration should not use env var but config-kourier

[nak3]

Currently some configurations especially external authorization use env variables as https://github.com/knative-sandbox/net-kourier#external-authorization-configuration instead of config-kourier configmap.

I think that there is no big reason for using env variable but we just used it because we haven't introduced config-kourier at that time.

Now, since new configurations are added in config-kourier, the env variables should be migrated into the configmap.

The same would probably apply for CERTS_SECRET_NAMESPACE and CERTS_SECRET_NAME used in caches.go

I would like to contribute in this but I am an absolute beginner if anyone can help me by providing steps it would be nice

[nak3]

Hmm... I think it is not a "good-first-issue" issue actually. It needs many steps for the change and one big concern is that some configurations might need to be loaded before ConfigMap informer's reconcile loop.
How do you think @ReToCode

[ReToCode]

Yeah, I think it could be more complicated than initially though. I haven't checked if any of the configs actually is affected by what you described. But it is probably better to start with a simpler issue @harshil1973.
