performance/readdir-ahead: limit cache size
This patch introduces a new option called "rda-cache-limit", which is
the maximum value the entire readdir-ahead cache can grow into. Since,
readdir-ahead holds a reference to inode through dentries, this patch
also accounts memory stored by various xlators in inode contexts.
