SERVER-51524 Rename internalQueryCacheSize to internalQueryCacheMaxEntriesPerCollection
Retains "internalQueryCacheSize" as a deprecated alias.
The new name better reflects the function of the parameter,
as it controls the number of cache entries allowed for each
collection's cache rather than the overall size of the cache
in bytes.
