Improvement suggestions in the source code

After looking at some aspects of the source code, I think we should starting thinking/considering about the below improvements in the source code in order to improve our further maintenance and development.
* Refactor some of the common aspects of the code to a separate package in the same repo and reuse from them. Breaking it down improves the readability, understanding and maintenance of the code. Example [instance](https://drive.google.com/file/d/1MSKJFdriPnZGsDe8082WSZwFayOHkQ5a/view?usp=sharing) of common code/logic across wrappers.
* Update README.md with proper documentation on implementation and testing details (Atleast for the most commonly used usecases)
* Use YAML configuration files to pass input params. As we have fairly large amount of arguments at this moment, I think we can use YAML configuration files and provide [templates](https://github.com/cloud-bulldozer/kube-burner/tree/master/examples/workloads) for them as it will help others as well to better adopt the usage.
* Use [**kwargs/dict](https://www.geeksforgeeks.org/args-kwargs-python/) to pass a large list of arguments across the methods. Example [instance](https://github.com/cloud-bulldozer/perfscale-managed-services/blob/8566fea6dcc7f41067270ce0672981cadc204e57/rosa-hypershift/rosa-hosted-wrapper.py#L526) of huge argument list.
* Add [doc string](https://peps.python.org/pep-0257/) to each function/method/class to improve readability as there seems to be lot many steps involved in the execution process.

I am open to other thoughts as well. Thank you
