Debug logging does not work on DEV

[dsmf]

Description

During testing #214 on DEV we noticed that log messages with level DEBUG do not appear in the logs (except for the CompositeLog) even though this should be the case.

This story is related to #293.

Current behaviour

Log level DEBUG is not logged.

Expected behavior

Log level DEBUG is logged.

Steps to reproduce the Bug

Run a query that executes code which has some logging with level DEBUG.

Might be related to irs-api/src/main/resources/application.yml:

logging:
  pattern:
    console: "%d %-5level %logger : %msg%n"
  level:
    root: WARN
    org.springframework: INFO
    org.eclipse.tractusx.irs: INFO

[dsmf]

log4j.xml is already set to debug, but still debug isn't logged, only INFO and above. As @ds-jhartmann mentioned in #396 (comment) this is probably overwritten by the values in application.yml.

DEBUG logs are now existing, adjustment of them was additionally done in PR #767.
Ticket is ready for PO-review, FYI @jzbmw .
