Upgrade Notes

• Because of a serious issue with Nova image cache management on shared storage, the image cache manager is now disabled by default. In cases where shared storage isn't in use, it can be re-enabled by setting image_cache_manager_interval = 40 in nova.conf.
• The 2.1 version of python-quantumclient is required if Nova is configured to use Quantum networking. See this review.
