Initial Environment Build Improvements

Getting a new reference architecture based environment initially deployed is still pretty cumbersome. Use the bootstrap label to track issues related to this. Overall notes can go in this issue.

Some ideas:

Scripting or bootstrap playbooks to help setup the first few VMs. Improve automation for the first few VM that come before the full playbook can be run.

DNS is in flux until the HA resolvers and both IPA servers are deployed. Think of ways to make this smoother for the implementer.

Better cmdr host setup docs. The jump host docs should include a full list of required packages. Improve instructions for Ansible install with pipx on distros like RHEL which do not have pipx in their repos.

Separate host_vars and group_vars from the main repo. Create a generator program that asks for some details like networks and domain name and generates the vars files needed for the refarch roles.
