"Missing or blank sdk key" log warning message upon importing ldclient

[pdsarin]

A warning is logged upon import of ldclient. IMO should either be logged at a lower level, or not at all as there's nothing I can do to prevent it.

WARNING 2016-12-13 23:53:09,950 config.py:43 - ldclient.util - __init__: Missing or blank sdk_key.

Got the same issue. It's because the Config object gets created in the init file without any arguments. Then inside the Config class is a check if the sdk_key is empty.
