Find available loop device for cinder-volumes

Browse Source 
Previously, Packstack used a fixed loop device (/dev/loop2) to create
the cinder-volumes test volume. This could create a conflict if the
loop device was already in use.

Using 'losetup -f' to find an available loop device should fix this.
