When you send message to exchange which is not exist current channel is closed and you need to reconnect. This is undesired. Also this patch separate sending fanout message and call/cast messages and don't raise exception if exchange doesn't exist for fanout messages. Change-Id: Ia556d0c1b219387892007925bb437664aaaccb69
