* rename ansible groups to use _ instead of -

k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating

Note: kube-node,k8s-cluster groups in upgrade CI
      need clean-up after v2.16 is tagged

* ensure old groups are mapped to the new ones

This replaces kube-master with kube_control_plane because of [1]:

  The Kubernetes project is moving away from wording that is
  considered offensive. A new working group WG Naming was created
  to track this work, and the word "master" was declared as offensive.
  A proposal was formalized for replacing the word "master" with
  "control plane". This means it should be removed from source code,
  documentation, and user-facing configuration from Kubernetes and
  its sub-projects.

NOTE: The reason why this changes it to kube_control_plane not
      kube-control-plane is for valid group names on ansible.

I had an issue with DNS not working because i didn't add the "kubernetes.io/cluster/$cluster_name" to the route table my subnets where using.

"kubernetes" is spelled wrong in the cluster tag example

The AWS IAM profiles and policies required to run Kargo on AWS
are no longer hosted in the kubernetes main repo since kube-up got
deprecated. Hence we have to move the files into the kargo repository.
