discovery: remove ResponseHeaderTimeout when discovery
discovery: remove ResponseHeaderTimeout when discovery

The discovery service doesn't return HTTP header early when watch
starts. This may trigger ResponseHeaderTimeout and cause the watch
request failed.

The fix on discovery service may take some time. Remove the
ResponseHeaderTimeout first so it behaves as before.
