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.
