cmd/coordinator: make gomote proxy 502 error include detail

Go 1.11 added ReverseProxy.ErrorHandler; use it to make the
httputil.ReverseProxy failures print the underlying error back to the
(trusted) client. (Normally the client isn't necessarily trusted
enough to get the full info)

Also, log more to stderr where we can search for it.

Updates golang/go#28365
