    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.
    See the oslo i18n guideline
    * https://docs.openstack.org/oslo.i18n/latest/user/guidelines.html#adding-variables-to-log-messages
