Research usage of log/slog package in favour of the current implementation

[k-gostev]

In go v1.21.0 a new package log/slog is introduced. Currently each component has its own logger implementation, which uses either log or sirupsen/logrus packages. We need to check how to unify the loggers and potentially use log/slog in favour of the current implementation. This may not only improve the code quality, but also it may help for reducing the binary size.
