Update various tests regarding disk creation
Update the tests that deal with disk creation and check if the nodes
field is populated correctly when creating a disk.

Update cfgupgrade tool
Create an upgrade function that adds a nodes field to each disk that is
attached to an instance. Also, add a downgrade function that removes the
nodes field and brings the config to the default state for 2.12.

Maintain consistency of nodes field
There are four scenarios in which the nodes field can change after the
disk's creation; when moving, replacing, converting or recreating disks.
For each scenario, update the nodes field accordingly.

Populate disk nodes when creating disks
When creating a Disk using the GenerateDiskTemplate function, fill the
nodes field depending on the disk template. There are three cases:
1) Internally mirrored disks (DRBD):
These disks are accessible from two nodes, so the nodes field will
include these. Their children (data, meta) are also accessible from
two nodes, therefore they will inherit the nodes of the parent.
2) Externally mirrored disks (Blockdev, Ext, Gluster, RBD, Shared File):
These disks should be accessible from any node in the cluster,
therefore the nodes field will be empty.
3) Single-node disks (Plain, File):
These disks are accessible from one node only, therefore the nodes
field will consist only of the primary instance node.

Add nodes field in class Disk
Add a field called "nodes" in the Disk class. This field will be a list
of Ganeti node UUIDs from which this disk is accessible. Also, update
the Haskell tests in order to adjust to this change.
