Improve service logging

[lsulak]

Feature Description

Our Lambdas for EventGate are not logging enough. Solution can be:

• Go over the Python code and add more logging. Validate existing messages and add and improve more.
• Consider to log via Powertools: https://docs.aws.amazon.com/powertools/python/latest/core/logger/ possibly
• Make sure that each log line holds certain executionID or something like that, so that we can correlate different log messages with the same Lambda runs

Problem / Opportunity

It's difficult to debug and fix issues on live deployment if the lambdas are not logging enough.

Acceptance Criteria

EventGate logs better
