Minor: config/metrics.properties not found

Noticed, when diagnosing a broken spark job.
Not sure if we should fix the environment, remove the loader if it's not used, or if it's expected, change this to INFO log without the ST.

We need to delete that config, this is a part of log->ELK configuration. It is not used by now, possible can be useful for k8s installation.
