Why set durable to true?
we found if set durable=false, when the first leader down and up later become follower, the new leader will sync itself data to the older leader which had become follower，this action might waste many times.
set durable=true might let queue data sync quick.it was suggest by our operation & maintenance engineer

1、add support to recreate queue when queue was delete,we can test delete queue in rabbitmq manamgent
2、add support to reconnect to rabbitmq
3、add suppert to rabbitmq has many host or ip，if rabbitmq.host="127.0.0.1,192.168.0.1"，amqpClient.js will use all the ip to test which can connect，this fix was for rabbitmq cluster which had no haproxy
