  - Merge "Revert "Apply apache state on proxy nodes""
  - Revert "Apply apache state on proxy nodes"

    Upstream fixed the salt-formula-horizon in commit 95387ec, by
    defining 8078 (and only that) port in Apache's ports.conf.
    This fixes the port 80 overlap, so running the `apache` high state
    after the `horizon` high state not only is unnecessary now, but
    also would lead to new breakage, since `apache` state would
    overwrite the ports.conf (removing 8078 and adding 80), i.e.
    creating a new port conflict and breaking Horizon port completely.

    This reverts commit eb4645206d6d74992fca3b8726ee2eebca97205f.
