QPID-3280: Performance problem with TTL messages.
When sending a large number of messages with nonzero TTLs to a
cluster, overall message throughput drops by around 20-30% compared to
messages with TTL 0.
The previous approach to TTL in the cluster is replaced with a simpler
"cluster clock". Also QueueCleaner is executed in the cluster timer,
and modified to be deterministic in a cluster.
