Sofer Athlan-Guyot 4ad99224bd Fix cinder_api_apache error during upgrade.
In I35c8d9985df21b3084fba558687e1f408e5a0878 we removed the
cinder_api_apache from step 2.  This cause the upgrade to fail as the
next task is using that variable.

Converting it to a fact in step 0 so that we can call it later.
