Process auth CheckResponse

[adam-cattermole]

Changes

Process the CheckResponse from the auth service.

Verification

• Build and deploy locally

make build && make local-setup

• Port-forward and watch logs in different terminals:

kubectl port-forward --namespace default deployment/envoy 8000:8000
kubectl logs -f deployment/envoy
kubectl logs -f deployment/authorino

• Make some requests based on the default authconfig:

curl -H "Host: test.a.auth.com" http://127.0.0.1:8000/get -i
# HTTP/1.1 401 Unauthorized

curl -H "Host: test.a.auth.com" -H "Authorization: APIKEY ndyBzreUzF4zqDQsqSPMHkRhriEOtcRx" http://127.0.0.1:8000/get -i
# HTTP/1.1 200 OK

See in envoy logs the /Check call and in Authorino the processing of the request.

That token is generated from our make targets?

Yep - it's coming from here https://github.com/Kuadrant/wasm-shim/blob/external-auth/utils/deploy/authconfig.yaml#L27 (I took this one from the authorino repo).

I'm going to update this to use the IAMALICE/BOB in a future PR just for ease of use

BTW, works like charm!
