Merge "Invalidate AZ cache when the instance AZ information is
different"
2. Reproduce steps:
* background data: 1000 instances, 10000 faults record in each instance
* list all instance details
Expected result:
* nova-api Host CPU load in a reasonable range, like: 85%
Actual result:
* nova-api Host CPU load persist 100%
NOTE: we collect all faults of each instance in db api (all results
loop), and only return the latest one in InstanceList object(all results
loop), I think we should return the latest fault of each instance in db
api, that can avoid an all results loop in InstanceList object.
