Make Ceilometer notifications non-blocking

Ceilometer notifications can be sent in a background thread, unblocking
the Swift proxy in case the RabbitMQ is not processing notifications
quick enough or even unavailable.

There is a default queue size of 1000 notifications. If more messages
are added to the queue these will be discarded, and a warning log entry
will be emitted.
