coldmoment ba8ad5e37f 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
and
* https://github.com/openstack-dev/hacking/blob/master/hacking/checks/other.py#L39
