Refactor codebase

[wesley587]

Overview

This pull request includes a refactoring of the codebase to enhance modularity and improve code readability. The changes aim to simplify the existing implementation, reduce code duplication, and adhere to established design principles.

Changes Made:

• To simplify the conversion process, replace Sigmac (legacy) with Pysigma.
• Add detailed documentation that provides a explanation for each process.
• Instead of using Pipenv, we are using Poetry as our virtual environment generator.
• Include custom exceptions to provide a better understanding of errors during the conversion process.
• Improve the abstraction level of the backend creation process.
• Create an output folder to store the rule output and log files.
• Create FileTools.py and DirectoryTools.py modules to facilitate common tasks related to directories and files.
• Create a Backend enum to represent all the available backend converters, eliminating the need for multiple if-else statements..

Benefits

• Improved code readability: The refactoring clarifies the purpose of functions, variables, and classes, making the codebase easier to understand and maintain.
• Enhanced modularity: By extracting reusable code into separate modules and classes, we promote code reusability, reduce duplication, and enable easier modifications in the future.

future work

Developing azure and splunk backend converter.
