meta: (re-)Implement Meta translator
The meta translator exposes details about glusterfs itself
in the form of a virtual namespace.
Loading the translator on the client side creates the
meta virtual view under $mntpoint/.meta by default. The
directory is not listed (even with ls -a) and can be
accessed by doing a "cd /mnt/.meta"
