Draft: Fix anthos logger minio

Yan Sushchynski [EPAM/GC]requested to merge
fix_Anthos_logger_minio into master

Fix two issues:

  1. log4js doesn't write logs in GCP, so it was changed to usual console
  2. Different versions of MinIO return different responses for ListObjects with and without Contents field, so we added handling such a situation.
