Improper loggers configuration precedence.

[ppalucki]

Describe the bug Command line loggers configuration is overwritten by values from config file.

To Reproduce Run wca with loggers from command line --log trace and configure loggers in config file like this

loggers:
  wca: info

Info level is set for all loggers - contrary to to what docs says https://github.com/intel/workload-collocation-agent/blob/master/docs/logging.rst#wca-logging-configuration

Expected behavior Trace logging will be enabled as described in docs.

Context:

• All versions are affected.
