From 769416f61343b6458529f023164b6ebb837eec3c Mon Sep 17 00:00:00 2001

Subject: Fix issues when cluster is run with persistence enabled.

- Handle partial failures (e.g. due to disk error): failing brokers shut down, others continue.
- Enable persistence in cluster tests.
- Correct message status in DeliveryRecord updates.
- Remove qpid.update queue when update complete - avoid it becoming persistent
