Code Issues Proposed changes

Expect paste.deploy and gnocchi/panko options 

The authtoken middleware has been printing warning log messages to
the API logs for all services, reporting unexpected conf keys. This
was traced back to paste.deploy adding 'here' and '__file__' and
both gnocchi and panko adding 'configkey' keys in wsgi apps though
these do not actually exist in the conf file. This change allows
for those keys without printing a warning that unnecessarily
confuses operators.

But it's kind of a hack, especially the configkey bit. We shouldn't
have to know about gnocchi/panko specifics like this. And it doesn't
address the comment in the bug about what is seen for ironic. So I
think there will still be more to do here.
