Fixed #28977 -- Changed local-memory cache to use LRU culling.
...
LRU culling turns every read into a kind of write to the cache: cache keys
are moved to the first position in the OrderedDict when they are retrieved.
The RWLock which permitted multiple readers while prioritizing a single
writer is obsolete since all accesses are now writes.

Add warning when using cache keys that might not work with memcached.
...
This means testing with local dev caches (not memcache) will warn
developers if they are introducing inadvertent importabilities. There is
also the ability to silence the warning if a dev is not planning to use
memcache and knows what they are doing with their keys.
