Convert the ScubaGoggles Orchestrator to a Class

[buidav]

💡 Summary

This issue is to track work in converting the ScubaGoggles orchestrator into a class.
Tied to epic #164

Motivation and context

There should no longer be a reason to tie ScubaGoggles design to mimic ScubaGear's design.
The current design decision to model ScubaGoggles after ScubaGear was for ease of portability of features from over there.
Converting Ochestrator to a class will help clean up the tangled code and provide better extendibility.

Implementation notes

The Orchestrator should relatively be easy to turn into a class as a lot of shared arguments were stuck into the argparse args dictionary which mimics ScubaGear's ScubaConfig class.

Acceptance criteria

• orchestrator.py is converted into a Class.
