Import logging and configuration functionality

OpenStack Oslo provides some awesome functionality for logging and
configuration handling, rather then writing our own we'll use theirs.

Additionaly, upstream is in the process of breaking these out into
python libraries so eventually we'll be able to completely drop the
included code.
