    Add a local registry guide for developers

    The guide is aimed at developers working in virtual environments that
    need to build or run several controller-0 setups (specifically, to
    developers in need of running the Ansible bootstrap playbook multiple
    times).

    By configuring a local registry and downloading the needed images
    beforehand, all subsequent installations can point to this local
    registry to download images from it to the controller-0. Not going to
    the internet everytime, devs are not subject to public registries' rate
    limits.
