feature/format: Merge Standard_D16as_v4 VM update

[StephanTLavavej]

Merge #1185 into feature/format so we can delete the old VMSS pool.

⚠️ Note to self: Commit this as a merge, not a squash!

I think you should be able to fast forward feature/format at this point.

Unfortunately, by configuring the branch protection policy to prohibit developers from pushing non-reviewed commits, we've also prohibited fast-forward merges from being pushed. (I wonder whether we should be maintaining feature/format before any work has been pushed to it, but it's really been so little effort that I haven't brought it up.)

We could simply wait until someone's ready to submit a PR, and then unlock the branch and fast-forward it. 🤷
