--debug raises a TypeError

[dmtucker]

See #19 (comment).

Here is a SSCCE:

>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)
>>> logging.debug('foo', bar='baz')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/ifs/home/dtucker/.pyenv/versions/3.6.7/lib/python3.6/logging/__init__.py", line 1912, in debug
    root.debug(msg, *args, **kwargs)
  File "/ifs/home/dtucker/.pyenv/versions/3.6.7/lib/python3.6/logging/__init__.py", line 1296, in debug
    self._log(DEBUG, msg, args, **kwargs)
TypeError: _log() got an unexpected keyword argument 'bar'

We seem to hit that here when --debug is used:

isilon_stat_browser/stat_key_browser/tagger.py

Line 73 in c0368c0

logging.debug('Expect key tag definitions at ', path=defs_path)
