Keystone middleware does not use configuration

I ran into this when trying to run ceilometer on devstack.
The ceilometer-api in devstack currently doesn't use a --config-file command-line option, so I tried adding that as well as creating a new config file for it in /etc/ceilometer/ceilometer-api.conf, but it doesn't seem to be using those values for the keystone middleware.

I've already sent a patch for devstack at https://review.openstack.org/#/c/14766/

But as you state, this bug is really about the config file not being taken into account. :(

There are a couple of issues. First, we're initializing the middleware before we read the config file, but then we're passing an empty dictionary to the middleware instead of the config object. I have a working version, but I need to figure out how to package it so it will work with mod_wsgi or another wsgi container.

Actually, I'm going to worry about the mod_wsgi stuff as a separate issue, since that's not really related and it didn't work already.
