Don't configure the root logger

As of today, importing dynaconf configures the handlers in the logging root logger, which renders the basicConfig useless:

This function does nothing if the root logger already has handlers configured for it.

Example:

>>> import logging
>>> logging.basicConfig(format="[%(asctime)s|%(levelname)s] %(message)s",
...                     datefmt="%Y-%m-%dT%H:%M:%S")
>>> logging.error("Something")
[2018-06-23T18:21:03|ERROR] Something

The collateral effect of importing dynaconf:

>>> import logging
>>> import dynaconf
>>> logging.basicConfig(format="[%(asctime)s|%(levelname)s] %(message)s",
...                     datefmt="%Y-%m-%dT%H:%M:%S")
>>> logging.error("Something")
2018-06-23 18:21:59,723 - root - ERROR - Something
