all previous training algorithms using that version of the model
should be deleted.

In case you want to perform extra security measures before deleting
a directory you can check that $modelversionoutputdir subdirectories
can only be named 'execution', 'evaluation' or 'testing'.

return: null

delete_output_dir($modeloutputdir, $uniqueid)   X-Ref
Delete the output directory.

This method is called when a model is completely deleted.

In case you want to perform extra security measures before deleting
a directory you can check that the subdirectories are timestamps
(the model version) and each of this subdirectories' subdirectories
