Refactoring and Enhancing Database Management and System Information Gathering

In this commit, we've made substantial changes to the DatabaseManager and SystemInformationGather classes to improve the functionality, efficiency, and maintainability of the system.

    Refactoring DatabaseManager: The DatabaseManager class was refactored to improve the separation of concerns. Initially, the DatabaseManager was responsible for creating an instance of SystemInformationGather, which was not ideal as it violated the Single Responsibility Principle. The responsibility of creating an instance of SystemInformationGather was moved to the FirstRunInit class, which is more appropriate as it is responsible for the initial setup of the system. This change improves the maintainability of the code and makes it easier to understand and modify in the future.

    Adding Database Connection Test: A method test_db_connection was added to the DatabaseManager to test the database connection before attempting to interact with it. This method improves the robustness of the system by ensuring that a valid connection exists before proceeding. It also provides a better user experience by providing a clear error message if the connection fails.

    Refactoring SystemInformationGather: The SystemInformationGather class was refactored to improve its functionality and efficiency. The methods ask_for_uplink_speed and ask_for_downlink_speed were modified to convert the user's input to Mbps immediately, reducing the need for conversion later. This change improves the efficiency of the system by reducing unnecessary conversions.

    Adding Services Table: A new table for services was added to the database. This table stores the services that the system should be aware of, with each service represented as a boolean value. This change improves the flexibility of the system by allowing it to handle a variable number of services. It also improves the efficiency of the system by reducing the need to parse the services from a string each time they are needed.

    Storing Total Bandwidth: The total bandwidth (the sum of the uplink and downlink speeds) is now calculated and stored in the system_info table. This change improves the efficiency of the system by reducing the need to calculate the total bandwidth each time it is needed.

    Error Handling and Debugging: Throughout the process, various bugs and errors were encountered and fixed. These included issues with method arguments, missing method calls, and incorrect method usage. Fixing these issues improved the stability and reliability of the system.

In conclusion, this commit significantly improves the functionality, efficiency, and maintainability of the system. The changes made adhere to good software engineering principles, such as the Single Responsibility Principle, and make the system more robust and user-friendly.
