Add support for v3 Keystone responses
Keystone master currently responds with v3 tokens. Preserve v2 support for stable/newton and earlier Keystones. Note that stable/ocata simply doesn't work. Related-Change: I5d0c18121ba4bf8e33209daa48b9d87864951362 Change-Id: I747de516ab69a47622eecbf8ab3faa34444b3ad5
