[martintc]

I'm submitting a

• bug fix
• feature
• documentation addition

What is the current behaviour?

Comtrya does not facilitate any management of groups, specifically, adding groups

What is the expected behavior?

Through a yaml file, comtrya will be able to add groups to the system

What is the motivation / use case for changing the behavior?

Base functionality for configuring production systems

Please tell us about your environment:

Version (comtrya --version): 0.7.4
Operating system: Pop_OS 22.04 LTS
Rust: 1.63.0
