md-cache: meta-data caching translator
This is a metadata caching translator which is well integrated with
glusterfs core framework and leverages some of the recent protocol
changes to do a better job at caching.
- It uses the attributes returned along callbacks of all calls to
update its attribute cache as frequently as possible without
issuing calls on its own (i.e, very low overhead)
- It caches attributes returned via readdirp into the inode contexts
corresponding to those entries (i.e, well integrated)
- It caches and updates xattrs and not just inode attributes (i.e,
eliminates the need for a separate xattr-prefetch translator)
In its current form it has a timeout based consistency model
