Fixes: #3003

Added the option to change log level for eventsource webhook.
Tested manually with the following yaml files:

apiVersion: argoproj.io/v1alpha1
kind: EventSource
metadata:
  name: webhook
spec:
  service:
    ports:
    - port: 12000
      targetPort: 12000
  webhook:
    example:
      endpoint: /example
      logLevel: info
      method: POST
      port: "12000"
      url: ""

will generate:
