/proc/fs/nfsd/reply_cache_stats has been present since v3.10 but
has no entry in Documentation/ABI/. Add one under testing/ that
documents the current field set, types, and parsing expectations.
This establishes a contract that parsers should match on field
name rather than line position, allowing fields to be added or
removed across kernel versions without breaking well-written
consumers.
