Handle optional JSON configuration files

Some JSON configuration files may be optionally defined, therefore this
needs to be handled when retrieving the file or loading it. When a JSON
configuration file is marked as optional and no file is found, an empty
filesystem path is returned.

Tested:
    No change to current use of getting/loading JSON configuration files
    Empty filesystem path is returned for an optional file not found
    Only an existing JSON config files are loaded
