RETRY_AFTER_SERVICE_UNAVAILABLE flag prevents onDisconnect from setting a delay

If you set client.getProperties.put(ClientProperties.RETRY_AFTER_SERVICE_UNAVAILABLE, true) and also set up a ClientProperties.RECONNECT_HANDLER, you hit some strange behavior.

When the connection is closed, the code call the user's ReconnectHandler.onDisconnect() method. If that method returns true, it then calls ReconnectHandler.getDelay() to determine when to reconnect - but that method is overridden by the internal RetryAfterReconnectHandler.getDelay() method, so it will always return 0\. I don't see a way to set a user-defined delay for the onDisconnect handler.
