Just because gluster calls it a confusing name does not mean we have to
repeat the confusion in libvirt - it is feasible to have a mapping where
we name it 'tcp' in the XML but map that to 'socket' in the command line
that eventually reaches gluster.  The question then becomes whether
using sensible naming in libvirt, but no longer directly mapped to
underlying gluster naming, will be the cause of its own set of headaches.
