Fixes #

Description

Add a script to add AKS machines pool to a cluster, being used directly in development. Currently not being used by any other command yet. To be a part of Machine API integration.

Note the unavailability of CLI, thus the need to use Azure REST.

Release Note

[Bryce-Soghigian]

is there a reason to do this outside of the makefile.az pattern we have been doing for all other setup steps?

This piece is just a quick dev tool. Integration with Makefile is more coupled to the existence of Machine API integration itself in the current plan (see #1102). It would be in a different PR.

Even the makefile sometimes shells out to individual scripts, no?

Yes. Though it is more that Makefile is a higher-level interface, and I think we should try to keep it "clean"--to reserve it for more-production-ready things. The list of files in this folder, on the other hand, is at lower level, so adding this less-relevant-to-production-Karpenter tool wouldn't hurt.
