	//     with, what zone it resides in, etc.).
	//  2. In response to (1), the management server designates this Envoy as a
	//     healthchecker to health check a subset of all upstream hosts for a given
	//     cluster (for example upstream Host 1 and Host 2). It streams
	//     HealthCheckSpecifier messages with cluster related configuration for all
	//     clusters this Envoy is designated to health check. Subsequent
	//     HealthCheckSpecifier message will be sent on changes to:
	//     a. Endpoints to health checks
	//     b. Per cluster configuration change
	//  3. Envoy creates a health probe based on the HealthCheck config and sends
	//     it to endpoint(ip:port) of Host 1 and 2. Based on the HealthCheck
	//     configuration Envoy waits upon the arrival of the probe response and
	//     looks at the content of the response to decide whether the endpoint is
	//     healthy or not. If a response hasn't been received within the timeout

	//     balances traffic to them without additional health checking. It may
	//     use inline healthcheck (i.e. consider endpoint UNHEALTHY if connection
