Feature request: Cloud native debug logging

The current feature to emit the debug logging to a separate log file is not playing well with a containerized "cloud native" framework where all logging is done to stdout/stderr and the log level determines what should be emitted.

As an improvement or feature request I would like Azurite -debug to be replaced with a -loglevel selector that would enable the debug printout to stdout instead of routing all debug level (not limited to) to a separate file.

As a ++ request to that end I would prefer if the log format was customizable as well, so I can disable timestamps etc. from the log output (these are logged by logging middleware, and the application should not emit those, imho).
