Upgrade Notes

 * The name of some middleware used by ceilometer changed in a backward incompatible way. Before upgrading, edit the  file for ceilometer to change   to  . For example, using sed -ri 's/oslo\.middleware/oslo_middleware/' api_paste.ini
 * The notification agent is a core service to collecting data in Ceilometer. It now handles all transformations and publishing. Polling agents now defer all processing to notification agents, and must be deployed in tandem.
 * A mandatory limit is applied to each request. If no limit is given, it will be restricted to a default limit.
