fqdn: Change error log to warning

There is no reason why the log level of "Timed out waiting for datapath
updates of FQDN IP information" log message should be an error. Change it
to a warning instead.

Add a reference to --tofqdns-proxy-response-max-delay parameter to make
this warning actionable.
