Keystone User IDs and Project IDs are used in unit tests, but _UUIDSentinels() class doesn't generate UUIDs without hyphens. This patch makes backward compatible modifications to _UUIDSentinels() class and introduces keystoneidsentinel global that could be used in the same way as existing uuidsentinel. Original "UUID sentinel" change: I214ff21b461fa1ca4b83476e1d0a763efe986217 Related-Bug: #1746747 Change-Id: Idb3e893cc03d64ad0522b5e4cedfa30c4f4a2a2f
