Set VM's machine name to match the VM name

[ruimarinho]

Hi,

If a VM is launched via Orchard with a specific VM Meta Name (we're using an ULID), the machine name is still considered to be admins-Virtual-Machine. Ideally, the name would match the Orchard's Meta Name. I believe this might require an update to tart, but I feel it's more of an issue with Orchard at this point giving its orchestration role.

Let me know if you'd like me to open the issue in the tart repository instead.
