Akihiro Motoki 5ae3e72c1f Return request-id in API response
Import RequestIdMiddleware from oslo which ensures to request-id
in API response. CatchErrorsMiddleware is also imported to ensure
all internal exceptions are caught outermost.
api-paste.ini is updated to use them.

KeystonAuthContext middleware is updated so that it uses
request-id generated by RequestIdMiddleware.

Add middleware to openstack.conf and import all modules
under middleware directory from oslo.
