Ansible

This draft captures the practical flow for building a bare-metal Kubernetes cluster with MAAS and DeepOps: commission the nodes, deploy the operating system, prepare the inventory, tune the Kubernetes variables for the environment, and run the cluster build with enough observability to make the result usable.

This draft captures a small but blocking issue in a DeepOps-style Ansible run where the remote Python environment was missing the pkg_resources module from setuptools.
