add timestamps to json log output of controller

[csantanapr]

Expected Behavior

Easy to detect via logs how long it took from receiving the webhook HTTP request until is done creating resources and replying back to the webhook originator (ie github)

Actual Behavior

Sometimes github would complain that the request time out because the response from the trigger listener controller didn't reply in time.

This is based on my vague understanding

Steps to Reproduce the Problem

1. Create event listener with proper trigger template and bindings
2. Expose to github the rul
3. Create webhook and generate a push event.
4. Check the logs of the eventlisternet pod to check how long it takes to perform the tasks
5. The json log lines do not contain a timestamp to help debug and troubleshoot to get an idea how long is the controller taking to process the request, interceptors, and create resources

Additional Info

Using tekton triggers provided via stable channel on OpenShift Pipelines Operator

Having the timestamp included in the logs definitely seems like a useful addition. In the meantime you can pass the --timestamps flag to kubectl logs to prepend each log line with the timestamp, e.g.:

$ kubectl logs el-webhook-listener-interceptor-7947c8c588-bsp8k --timestamps
