Modify the current cloudwatch logic to include necessary switch on output type.   Rename cloudwatch methods to include gcp logging. 
If gcp loging, we will project the SA token into the pod.  We do not need the env vars, rather it should get everything from the pod secret "service_account.json" data.

oc get secret gcp-secret -ojson | jq -r '.data."service_account.json"' | base64 -d
