Improve ansible configuration

[levibostian]

• [ ] There are no roles included in the project. The playbook is referring to all remote roles.
  • Each role has good testing around it. Testing that proves: you can perform an action 2+ times with the same result, reverse changes (comment out a line and uncomment it later).
• [ ] use hardening ssh role? This role seems like it can do all that I need for configuring SSH and more best practices.
• [ ] use hardneing os role? This role might have some best practices that I am currently not doing.
• [ ] the galaxy requirements file, have it install specific versions of the roles/collections.
• [ ] This unattended-upgrades role looks good.
