unable to manually generate an ansible.cfg for config download in older versions

[Alex Schultz]

We switched to config download by default in Rocky and provided a cli command that could be used to generate one for manually running the ansible playbooks. If you use the config download command in Queens, no ansible.cfg is provided in the output directory which leads to users possible using less than ideal default ansible configurations. We can backport a basic version of the `openstack tripleo config generate ansible` command.

    Generate ansible.cfg for UC/standalone deployments

    Add CLI command that allows to generate and manually
    customize the default ansible configuration used with
    UC/standalone deployments. Use the config generator
    from tripleo common ansible actions for that.

    If there is no pre-created user's ansible.cfg in
    --output-dir, generate the default one with as a part of
    the deployment command.

    NOTE: This is a queens only version that does not include the user cli
    option as it's not implemented in Queens.
