Deliver puppet modules on slave nodes using packages

Currently, we install fuel-libraryX.Y package(s) on the master node and then right before starting actual deployment we rsync [1] puppet modules (one of installed versions) from the master node to slave nodes. Such a flow makes things much more complicated than they could be if we installed puppet modules on slave nodes as rpm/deb packages. Deployment itself is parameterized by repo urls (upstream + mos) and this pre-deployment task could be nothing more than just installing fuel-library package from mos repo defined for a cluster. We would not have several versions of fuel-library on the master node, we would not need that complicated upgrade stuff like we currently have for puppet modules.
