Configure logging for onedns *application* code

By default onedns's logger has no formatters and a NullHandler so that

other developers using onedns as a library can configure logging as
|
|
they see fit. This method is used in onedns's application code (i.e.
|

the 'onedns' command) to toggle onedns's application specific
