latest kernel get installed on the hosts, but hosts done get rebooted

[ajarr]

When testing, Jeff Layton observed that latest kernel get installed on hosts, but hosts don't get rebooted afterwards by the ansible scripts.

In pre-config.yaml, I see all packages are updated using 'update_packages' section. Then we install a bunch of packages. Maybe installing them also somehow installs the latest kernel on the hosts?

Probably, I think we just need a reboot task if packages were updated. Would you like to work on that @ajarr?
