docker_storage_setup
=========
This role coverts docker to go from loopback to direct-lvm (the Red Hat recommended way to run docker).

It requires the block device to be already provisioned and attached to the host.

  Notes:
  * This is NOT idempotent. Conversion needs to be done for it to be idempotent
  * This will remove /var/lib/docker!
  * You will need to re-deploy docker images
