[Serve] http proxy timeout are not getting triggered

[GeneDer]

What happened + What you expected to happen

When the health check hangs, longer than the default timeout of 30s, http proxy should timed out and eventually fails the proxy and restart it. Currently there is a bug where the default health check period is 10s and it recreates a new health check object reference and will never get to the timeout case to fail the check. Thanks to @edoakes pointing this out.
