logging-fluentd redirects log to /var/log/fluentd/fluentd.log after recent update

Issue

• Since we have the newer logging-fluentd image (v3.9.57) running, the /var/log is filled on our openshift nodes. We read in the documentation that one can redirect the output to STDOUT by setting the environment variable LOGGING_FILE_PATH=console. By setting that variable in the DaemonSet fluentd creates a file called console under /opt/app-root/src and redirects (2>&1) to that file.
