Inspiration from another playbook

Hello Adnan,
I found an [interesting article by Jimmy Olsen][article] that describes thoroughly a playbook to update/upgrade Ubuntu hosts, very similar to yours.

It seems to me that it has some more details, like an user prompt, and some additional checks. Do you think they might be added to your (way more reusable) role?

Would you like a PR?

Good job with this role,
Valerio
