Replace a VM playbook should add correct number of disks

[VickieKarasic]

User story

As an Ops person, I want to make sure that when I run the Replace a VM playbook, it replicates the number of attached hard disks, not just the total amount of disk space.

Acceptance criteria

The playbook should add the same number of disks as the original machine had.

Implementation notes, if any

The original catalog-qa1 had 2 disks of 30GB each. When we replaced catalog-qa1, we noticed that it only came up with one disk at 60GB. When we expanded the logical volume, it only expanded to 30GB. (For example, if you look in vSphere, you see one hard disk at 60GB, whereas in the original machine, there were 2 hard disks with 30GB each).
