feat(logging): Implement structured logging

[srebhan]

Summary

Structured logging is a machine-readable way of outputting logs and useful when automatically processing the produced logs. This PR implements a structured log-target producing JSON formatted structured logs. It is output to a logfile, if specified, or to stderr otherwise similar to the usual text logger. Additionally, the PR deprecates the file and stderr targets and replaces them with a text target as that's what the output is. The decision to use a file or stderr is the done based on the logfile setting
