Open Stack

To anyone who cares,

I made a try to use kombu 2.5 (specifically its reconnecting logic), with
oslo.messaging (which uses kombu's reconnecting logic after kilo). No
matter whether heartbeat is enabled or not, there are truly many problems.
NoneType Error [1], eg.
I have to manually backport several commits from upstream of kombu to
bypass those NoneType errors.
