Migration from Custom Logger to Log/Slog

[mastercactapus]

What problem would you like to solve? Please describe: Our current custom logger, despite its functionality, has caused confusion for new engineers. The standardisation of our logging system could improve understandability and maintainability.

Describe the solution you'd like: A transition from our existing custom logger to the log/slog interface should be made. While keeping logrus as it is used in the background, using the standard log/slog interface will provide more clarity for newer engineers.

Describe alternatives you've considered: The plausible alternative is to stick to our current custom logger. Though it serves its purpose, the introduction of a structured logging package in Go and previous experiences make a shift to log/slog a more attractive option for the times ahead.

Additional context: To facilitate a smooth transition, the initial step should be a comprehensive documentation of the current log approach and flow that includes elements such as config and references, operational detail, and any special features that should be preserved and discussed.
