The patch replaces oslo.rpc by oslo.messaging. The important changes: - On the collector, the queue name and the topic are now the same (ie: metering, instead of ceilometer.collector.metering for the queue and metering for the topic) - Same for the alarm partitionner the queue is no more prefixed by ceilometer.alarm. Implements switch-to-oslo.messaging Change-Id: Ia5e4ff1dd1d419c090b8039627234ae7f07e8660
