Incompatibility between Kopf and New python-json-logger Version Causes Startup Crash"

[leroyshirto]

Long story short

A new version of python-json-logger breaks compatibility with kopf, causing kopf to crash with the error No module named 'pythonjsonlogger.jsonlogger' due to the dependency not being pinned. This issue is documented here: nhairs/python-json-logger#29. Pinning python-json-logger to version 2.0.7 resolves the problem.

python-json-logger changed their pythonjsonlogger.jsonlogger to pythonjsonlogger.json in python-json-logger>=3.1.0

Install python-json-logger==3.0.0 until this is resolved
