PSI-specific symlink evaluation

[sbliven]

checkMetadata.go:395 contains the following:

	// NOTE: this part seems very PSI specific
	// [if lvl.1 (or 2?) path == "sls" and lvl.3 (or 4?) path == "data"] => evaluate symlinks in path
	parts := strings.Split(sourceFolder, "/")
	if len(parts) > 3 && parts[3] == "data" && parts[1] == "sls" {
		var err error
		sourceFolder, err = filepath.EvalSymlinks(sourceFolder)
		if err != nil {
			return "", fmt.Errorf("failed to find canonical form of sourceFolder:%v %v", sourceFolder, err)
		}
		//log.Printf("Transform sourceFolder %v to canonical form: %v", val, sourceFolder)
		metaDataMap["sourceFolder"] = sourceFolder
	}

Can this code be deleted? If not, can it be replaced with a more generic option to resolve symlinks in sourceFolder?

This issue should be discussed with our beamline scientists.
