Libvirt historically stores storage source path including the volume as
one string in the XML, but that is not really flexible enough when
dealing with the fields in the code. Previously we'd store the slash
separating the two as part of the image name. This was fine for gluster
but it's not necessary and does not scale well when converting other
protocols.
Don't store the slash as part of the path. The resulting change from
absolute to relative path within the gluster driver should be okay,
as the root directory is the default when accessing gluster.
