NFS: DNS resolver PipeFS notifier introduced
This patch subscribes DNS resolver caches to RPC pipefs notifications. Notifier is registering on NFS module load. This notifier callback is responsible for creation/destruction of PipeFS DNS resolver cache directory. Note that no locking required in notifier callback because PipeFS superblock pointer is passed as an argument from it's creation or destruction routine and thus we can be sure about it's validity.
