Open Stack

Hi,

We may have missing packages when the user is adding a new role to its
roles_data file and the base image is coming from previous version.

The workflow would be this one:
 - install newton
 - upgrade to ocata
 - add collectd to roles_data and redeploy the stack

For instance if one is adding
OS::TripleO::Services::Collectdservices::collectd in an ocata env coming
from an upgraded newton env, he/she won't have the necessary packages
(for instance collectd-disk).  The puppet manifest will fail has the
package is missing and puppet doesn't install package.  The upgrade
task[1] is useless as the new role wasn't added during the upgrade but
after.

I don't see any easy way to solve this.  Basically we need a way to keep
in sync base image between release without using the upgrade_tasks,
maybe in the tripleo-package one ?

This shouldn't be a problem with container, but everything before pike
is affected.
