notifier middleware broken by oslo.messaging

[gordon chung]

the audit and notifier middlewares in openstack.common.middleware are broken due to switch to oslo.messaging. the notifier middleware is in process of being graduated to oslo.messaging. the audit middleware will be graduated to pyCADF library.

incoming fix is to drop common code as it only works again openstack.common.notifier system. instead the audit and notifier middlewares will work against pyCADF and oslo.messaging libraries respectively. both libraries are currently part of Nova already.

    notifier middleware broken by oslo.messaging

    audit middleware in oslo-incubator is incompatible with oslo.messaging.
    an oslo.messaging compatible version is available in pycadf library.
    remove broken oslo-incubator code in this patch.

    also add middleware/request_id to openstack-common.conf so we continue
    to pull in request_id middleware but not audit/notifier.
