Affected functionality
Adds metrics around LRU cache entry operations. On every LRU cache entry add, update, and removal, a counter is incremented. After each call to update entries and SVIDs, the total size of the entry and SVID map is reported.
Also renames the ExpiresAt field to SVIDExpiresAt in the StaleEntries struct and adds an additional log field entry_id to a log.
Description of change
Additional observability into LRU cache entry operations and memory usage.
