I'm curious does this have a knock-on benefit regarding configure times? |

Allows clusters to be deployed without outbound internet access. Key configuration changes:
environments/common/inventory/group_vars/all/proxy.yml, making it easier to define a proxy using basic authentication.proxy_removeallows removing proxy configuration at the end of Ansible runs. This defaults tofalsefor clusters buttruefor build VMs. NB: This is a change in behaviour; before if theproxygroup was enabled for the build then the proxy configuration would have been left in the image.openondemand_install_apps_extrato simplify installing additional OpenOndemand Apps.See docs/experimental/isolated-clusters.md for more information.
Design notes:
dnf_repos:disable_repos.yml. This meansansible.builtin.dnftasks during site.yml do not trigger dnf cache updates and hence complete successfully (assuming relevant package(s) are actually installed).fatimage.yml, with additional guards forappliances_modeadded to avoid running them during site.yml.
