Webhook Health Check

For webhook or webhook extended event sources such as github, gitlab, sns, slack, Storage GRID and stripe, besides the endpoint configured in the spec, an extra endpoint :${port}/health will also be created, this is useful for LB or Ingress configuration for the event source, where usually a health check endpoint is required.

For example, the following EventSource object will have 4 endpoints created, :12000/example1, :12000/health, :13000/example2 and :13000/health. An HTTP GET request to the health endpoint returns a text OK with HTTP response code 200.
