gRPC health checks on Kong

How to perform gRPC health checks on Kong which is exposed behind AWS ALB. Reference: Health checks for your target groups - Elastic Load Balancing

If the protocol version is gRPC, specify the path of a custom health check method with the format /package.service/method. The default is /AWS.ALB/healthcheck.

The requirement is to do a health check on Kong and not pass it through to an upstream.

@hbagdi would you have any thoughts here?
