+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
