Summary: Ref T7707. Caches availability on users to reduce the cost of loading handles. This cache is very slightly tricky to dirty properly. Test Plan: - Use DarkConsole to examine queries; saw cache hits, miss+fill, dirty. - Saw availability change correctly after canceling, joining, declining events. - Saw no queries to Calendar for pages with only availability data.
