Open Stack

Quick note: There are no 2.2X releases of oslo.concurrency. It looks 
like we're probably talking about 3.2X.

Glancing at the current requirements I would guess it's because a lot of 
services are requiring 3.26: 
http://codesearch.openstack.org/?q=oslo.concurrency&i=nope&files=requirements.txt&repos=

Maybe there's a mismatch with the requirements repo that is capping it 
at 3.25.1 when some of the other repos moved on to requiring 3.26?
