This splits code in apt_update_upgrade into 'apt-update-upgrade' and 'apt-configure' and 'package-update-upgrade-install'. The 'package-update-upgrade-install' then uses the generic distro package mechanisms for acheiving the same goal. Also, adjusts some of the reboot backoffs and log flushing/sleeping that was happening there.
