@Override
  public boolean isTraceEnabled(final Marker marker) {
    return delegating && super.isTraceEnabled(marker);
  }
Overrides is-enabled checks to avoid performance penalties in the following cases:
- log level is lower than INFO
- log configuration has filters

If delegating is true then it will always delegate to ExtendedLoggerWrapper for is-enabled
checks.
