apache2 can be start of sysv script before o-r-c configures it blocking the o-r-c run

[Michael Kerrin]

If apache2 gets started by sysv script before o-r-c configures it to listen only on certain port then apache2 will block haproxy element from configuring haproxy and those blocking o-r-c from configuring and restarting apache2.

We will need to enable apache2 after configuring it. So apache2 should not come up till we are ready.

This is a race we caught in our internal CI but with certain changes coming to the heat templates to add more dependency control we will probable see more of this.

How about the progress of this bug? I have encountered this problem.
the same as: https://bugs.launchpad.net/tripleo/+bug/1393643.

may be we can simply stop apache2 before starting haproxy
