Edd Robinson d2923c7bf9 Add hints as to how to pre-allocate entry values 
Currently, whenever a snapshot occurs the Cache is reset and so many
allocations are repeated, as the same type of data is re-added to
the Cache.

This commit allows the stores to keep track of the number of values
within an entry, and use that size as a hint when the same entry needs
to be recreated after a snapshot.

To avoid hints persisting over a long period of time they are deleting
after every snapshot, and rebuilt using the most recent entries only.
