What happens if the server in upstream is dynamic changed ? Now health check will ignore the new incoming server.

[zhuqiuyang]

when call hc.spawn_checker the upstream is: upstream test { server 127.0.0.1:8080; }

But some time, upstream update to :upstream test { server 127.0.0.1:8080; server 127.0.0.1:8081; }

Health Check will ignore 127.0.0.1:8081 server, because that peer not in upstream, when i first call hc. spawn_checker.
