The notifier from Oslo has been sync'd with Keystone and it has been used to deliver notifications using the log_notifier and rpc_notifier. By default the rpc_backend is impl_kombu.py and I can verify the notifications arrive on the queue. When using impl_qpid as the rpc_backend and sending a notification, the process hangs attempting to establish a connection with qpid.

Steps to reproduce:
1.) Update keystone.conf to send notifications
# ======================= NOTIFICATIONS =================================
notification_driver = keystone.openstack.common.notifier.rpc_notifier
rpc_backend = keystone.openstack.common.rpc.impl_qpid
2.) restart Keystone
3.) create/update/delete project or a user (both resources will send a notification)
$ keystone tenant-create --name my_project

After setting a break point I have followed the call in to qpid code before it hangs. I am not sure if the problem here lies in impl_qpid or possibly something with qpid code. I have been able to reproduce this on qpid 0.20 and 0.22.

The following is a trace with pdb included:

I've tried this using config options for qpid username and password and leaving them as default, neither work for establishing a connection.
