Open Stack

I agree that we shouldn't need to sync as we should be able to just update
the fuel-library package. That being said, I think there might be a few
issues with this method. The first issue is with plugins and how to
properly handle the distribution of the plugins as they may also include
puppet code that needs to be installed on the other nodes for a deployment.
Currently I do not believe we install the plugin packages anywhere except
the master and when they do get installed there may be some post-install
actions that are only valid for the master.  Another issue is being
flexible enough to allow for deployment engineers to make custom changes
for a given environment.  Unless we can provide an improved process to
allow for people to provide in place modifications for an environment, we
can't do away with the rsync.

If we want to go completely down the package route (and we probably
should), we need to make sure that all of the other pieces that currently
go together to make a complete fuel deployment can be updated in the same
way.
