Automated adapter unit tests

[Kircheneer]

Environment

• DiffSync version: latest

Proposed Functionality

Provide a framework for the automation of adapter unit tests.

Use Case

It gets cumbersome to test updating of each attribute on a diffsync model manually for example, it would be great if we could find some pattern that makes this easier on the user.

I gave this a brief looking into and I believe it will only be possible if we narrow down the scope and do this in https://github.com/nautobot/nautobot-plugin-ssot instead. I will leave this open for now in case other people have ideas.
