Move package management related config to system_packages

boostrap_os initial purpose is to provision Python on managed nodes
which don't have it pre-installed.
Some OS specifics tasks here are in fact related to package management
(installing extra packages sources like epel, package manager proxy
settings).

Move all of those to system_packages, allowing to eliminate some call to
the setup module.
