Doc Text:	In prior releases, a race condition existed in the ironic-conductor hash ring code. A hash ring can be None under load, but this causes an internal server error: 'NoneType' object has no attribute '__getitem_'. This release fixes the race condition, and ironic API operations no longer fail with 'NoneType' object has no attribute '__getitem_'.	Story Points:	---
