test(cluster): missing log level field in generated conf files
I just noticed that for AMF, SMF and SPGWU, you were creating the configuration file.
The LOG_LEVEL field was missing, and the default value becomes off.
See https://jenkins-oai.eurecom.fr/job/OAI-CN5G-COTS-UE-Test-Dev/49/
With this fix, I set the log-level to info: https://jenkins-oai.eurecom.fr/job/OAI-CN5G-COTS-UE-Test-Dev/50/
