py-structlog: update to 17.2.0

17.2.0:
- ``structlog.stdlib.ProcessorFormatter`` now accepts *keep_exc_info* and \ 
*keep_stack_info* arguments to control what to do with this information on log \ 
records.
  Most likely you want them both to be ``False`` therefore it's the default.
- ``structlog.stdlib.add_logger_name()`` now works in \ 
``structlog.stdlib.ProcessorFormatter``'s ``foreign_pre_chain``.
- Clear log record args in ``structlog.stdlib.ProcessorFormatter`` after rendering.
  This fix is for you if you tried to use it and got ``TypeError: not all \ 
arguments converted during string formatting`` exceptions.
