Reduce ITDE log level in NC

[ckunki]

Current situation

The tests in the notebook connector involving the ITDE (see example) create large amounts of logs which make navigation, searching and analysis quite hard.

They are producing thousands of lines like

DEBUG luigi-interface:worker.py:995 Asking scheduler for work... 
DEBUG luigi.scheduler:scheduler.py:711 Starting pruning of task graph 
DEBUG luigi.scheduler:scheduler.py:715 Done pruning task graph 
DEBUG luigi-interface:worker.py:944 Done 
DEBUG luigi-interface:worker.py:945 There are no more tasks to run at this time 
DEBUG luigi-interface:worker.py:948 SpawnTestDockerDatabase ... 

Proposal

The current ticket therefore requests

• in NC's call to api.spawn_test_environment()
• to add a parameter log_level="INFO"

Regarding case-sensitivity

See ITDE user guide.

luigi_log_config.py uses

logging.getLogger(...).level = logging.getLevelName(log_level)

Experiments:

>>> import logging
>>> logging.getLevelName("INFO")
20
>>> logging.getLevelName("info")
'Level info'
>>> logging.getLevelName(logging.INFO)
'INFO'
