WIP - Updating AKS Cluster and dependent resources definitions

[ytimocin]

Description

Initial work on updating the definitions in the test/infra/azure folder that defines an AKS Cluster (that we use for long-haul testing) and all the dependents.

As of 24 Nov 2023, after the initial creation of resources here are the policies that fail:

We're building up the akscluster module, me hearties
Adding features and fixing errors as we go
We'll make a private cluster and an arc node pool
And update the README so everyone will know
