    Keystone server support for user groups
    
    This implements the server side of groups of users.  This
    set of code provides all the crud functionality for groups as
    well as the corresponding support for role assignments.
    
    The following deficiencies existing with the current version and
    will be corrected ahead of Grizzly-2
    
    1) There is only placeholder support for LDAP (Bug #1092187)
    2) Domain role grants are accepted but not yet honored (Bug #1093248)
    3) Token invalidation does not occur with group changes (Bug #1093493)
    
    This update also fills in missing v3 grant unit testing and v3 grant
    support within the kvs backend.  In addition, there is a fix for
    Bug #1092200 (uncaught exception when listing grants)
