Augment oslo's default log levels with nova specific ones.

Thanks to I49a82c5b3446784d254ca558f51b6c3e5c2028eb, we can augment
oslo's set of default log levels with project specific ones.

Add keystonemiddleware as warn level since its verbose and nova isn't
trying to debug keystonemiddleware.

Add routes.middleware since this generates 3 log entries per API request
and doesn't help make debugging easier.

Fix FloatingIP.save() passing FixedIP object to sqlalchemy

This prevents the FloatingIP.save() method from passing the
calculated FixedIP object to the sqlalchemy floating_ip_update()
function, which would expect it to be an SA object. It also
aborts any attempt to save the object with a modified fixed_ip_id
linkage, as associate/disassociate should be used for that.

This also fixes a bug where FloatingIP expects the result of
floating_ip_update() to be a FloatingIp SA object.
