Cannot specify target container when adding disks to a virtual machine resource

[sbourdeaud]

Problem: When creating a virtual machine resource and specifying additional data disks, there is no way to specify the target storage container in disk_list, which means all data disk are added to the SelfServiceContainer by default, even if the VM itself was created in a different container.

Proposed solution: The API in Prism lets you specify a storage container when you add a disk to a VM. This should be added to the disk_list attribute in the nuanix_virtual_machine resource specification.

After checking, it seems only API v2 has a way to specify a target container. v3 does not offer that facility. Looks like this will be added in 5.13 (https://jira.nutanix.com/browse/ENG-212697)

Hello, @sbourdeaud I added the necessary changes to reference a container in the VM, you can check them in the PR #138.

Let me know if you have a comment or concern, thanks.
