    Updated parsing of catalog to handle bad format

    Don't assume that the service catalog is well-formed, added code
    to safely parsing the catalog.

    Parsing of region from service catalog has been fixed as well.
    'region' has been deprecated in the Keystone V3 catalog in favor of
    'region_id'. Fix how region is extracted by checking 'region_id' then
    fallback to 'region'.
