Create lvm.py module containing helper API for LVM

Currently there are some LVM API calls in 'nova/virt/libvirt/utils.py'
and also many other APIs are there.
To make a role of the code be clear, I would like to suggest to
create 'nova/virt/libvirt/lvm.py' and move APIs which are related
to LVM to lvm.py.
