Refactor Apache httpd setup

All Apache httpd setup has been moved to a new helper script,
kolla_httpd_setup. This includes the existing clean of /run/httpd,
/var/run/httpd, /tmp/httpd etc.

Horizon has an additional bit of Apache config for Debian/binary, which
has been kept in extend_start.sh for horizon.
