Update configurations files with changes from "rpmnew" files

[JGoutin]

Ensure configuration updated from packages are merged in the Ansible configuration.

Also check for "rpmnew" files that are not modified by the role but that may be updated.

rpm -Vlc --all
find / -print | egrep "rpmnew$|rpmsave$"

Files from the role managed.

Other files should likely be managed on case by case basis using rpmconf -c then rpmconf -a.
