Remove lxc attaching/detaching of volumes
Remove lxc attaching/detaching of volumes

Remove lxc attach and detach of volumes since this
will be handled by libvirt in upcoming versions of
libvirt.

This is expected to be in libvirt 1.0.1 or 1.0.2.
This resolves (LP: #1067638) and (LP: #1009701)

This removes a non-functional feature of the
lxc driver with functionalilty that is coming
with newer versions of libvirt.
