plugin/proxy: skip hc for https_google (#1272)

Browse source 
If protocol is https_google we do the health checks wrong, i.e. we're healthchecking the wrong
endpoint, hence the health check code below should not be executed. See issue #1202.
This is an ugly hack and the thing requires a rethink. Possibly in conjunction with moving
to the *forward* plugin.
