    Fix config group not found error

    Two parts to this fix:

    * add a call to oslo.config.cfg.import_group so that the function
      that checks a uri against the configured white/blacklists can
      access them
    * move the location where these options are defined into the
      module's __init__ so that they can be imported without causing a
      circular import (which happens if you import them from their
      current location)
