Refactor and reorganize grafana-docs-monitoring project for better maintainability

[Persimmonboy]

This issue aims to refactor and reorganize the grafana-docs-monitoring repository to improve its maintainability and scalability. By implementing a more modular and configurable structure, we can simplify development and operational processes.

Tasks:

#### 1. Create Configuration Module
- Establish a config directory to house all environment-specific settings rather hardcoding them in scripts.
- Implement config/settings.py to manage settings from environment variables.
- Optionaly introduce .env files for different deployment environments to easily switch and manage configurations.

#### 2. Database Module Setup
- Set up a database module under the modules directory.
- Create for example connect_to_db() function in database.py to manage database connections using configurations from config/settings.py.

3. GitHub and Gitea API Module

• Introduce a github_api.py and gitea_api.py file in the modules directory for GitHub and Gitea API interactions respectively.
• Ensure all API interactions are wrapped in try-except blocks to log and manage exceptions effectively. This includes handling API rate limits, connection errors, and data processing errors.
• Centralize common functionality such as error handling, logging, and retry logic in a utility module or class to be used by both API modules.

#### 4. Scripts for Routine Tasks
- Organize operational scripts in the scripts directory.
- Utilize functions from modules for tasks like updating database data or checking GitHub/Gitea issues.

5. Refactor Environment Handling in request_changes.py

• Create a dictionary with environment names and their corresponding configurations.
• Replace direct function calls with a for loop iterating over the dictionary.
• Add logging to indicate the start and end of processing for each environment.
• Rename main functions for better clarity.

6. Main Execution Script

• Develop main.py at the project root as the entry point for running scripts.
• Keep main.py simple, facilitating easy command-line or scheduled execution of tasks.

Expected Outcome:

Achieving these tasks will enhance the project's architecture for better maintainability and scalability, simplifying both development and operational processes.
