Switch VCP to LVM based partitions

This patch switches qcow builder to build VCP with lvm based
partition inside. The disk split to 3 partitions:

  1. 1MB partition needed for GPT
  2. 1Gb boot partition
  3. LVM partition

On LVM the following list of partitions is created:

  * /
  * /home
  * /tmp
  * /var/tmp
  * /var/log
  * /var/log/audit

Important: this will break default growroot cloudinit functionality.
To grow LVM automatically the foolowing data should be added to
cloudinit user-data.cfg

user_data:
  growpart:
    mode: auto
    devices: ['/dev/vda3']
    ignore_growroot_disabled: false
  runcmd:
    - [ 'pvresize', '/dev/vda3' ]

The name of LVM partition might be changed depending on the disk
model specified in VCP, by default is virtio.

Further partitioning size tuning should be done via linux formula.
