Describe the bug
The Metric operation is not able to find subclasses of a plugin if the plugin has not been imported from anyway in the application.
The same occurs with the transformations: The Metric operation is not able to find a transformation if there is not any import of such transformation in the code of your application. For instance, Metric operation won't find PySAT to FM if in your code you never import the PySAT2FM transformation in any part.
