Add ability to use LVM volumes for VM disks.

Implements LVM disks support for libvirt driver.

VM disks will be stored on LVM volumes in volume group
 specified by `libvirt_images_volume_group` option.
 Another option `libvirt_local_images_type` specify which storage
 type will be used. Supported values are `raw`, `lvm`, `qcow2`,
 `default`. If `libvirt_local_images_type` = `default`, usual
 logic with `use_cow_images` flag is used.
Boolean option `libvirt_sparse_logical_volumes` controls which type
 of logical volumes will be created (sparsed with virtualsize or
 usual logical volumes with full space allocation). Default value
 for this option is `False`.
Commit introduce three classes: `Raw`, `Qcow2` and `Lvm`. They contain
 image creation logic, that was stored in
 `LibvirtConnection._cache_image` and `libvirt_info` methods,
 that produce right `LibvirtGuestConfigDisk` configurations for
 libvirt. `Backend` class choose which image type to use.
