refactor: Migrate away from deprecated ILogger interface to PSR-3

Mostly replace `ILogger` with `LoggerInterface` and some minor cleanup (constructor property promotion).
Some places used the deprecated `logException` this is easy to migrate by simply use the appropriate loglevel on the logger
and place the exception under the `exception` key in the context.
Also the manual checking of the configured log level is not needed, as this is already done by the logger.
