    Add a hacking rule for string interpolation at logging
    
    String interpolation should be delayed to be handled
    by the logging code, rather than being done
    at the point of the logging call.
    So add a hacking rule for it.
    
    See the oslo i18n guideline.

Bug description:
  String interpolation should be delayed to be handled by the logging
  code, rather than being done at the point of the logging call.

  Wrong: LOG.debug('Example: %s' % 'bad')
  Right: LOG.debug('Example: %s', 'good')

  See the following guideline.

  * http://docs.openstack.org/developer/oslo.i18n/guidelines.html
  #adding-variables-to-log-messages

  The rule for it should be added to hacking checks.
