    Fix: configure etc-hosts for overcloud group

    Change the etc-hosts role to run on the overcloud group, as using
    ``ansible_play_hosts_all`` would exclude hosts when running with a
    limit.

    Also change the gather-facts-delegated role to run on the overcloud
    group. The delegated task needs to be included separately as the hostvar
    ``ansible_host`` cannot be set dynamically based on a loop item in one
    task. We loop over the batch indices here so that the tasks are included
    in parallel, rather than in series.
