Subject: [PATCH] Hide test options

This PR hides the `--unittest-mode` option that is used to treat all warnings as errors which is helpful when testing things, but is not intended to be used elsewhere.

The option is simply not shown in the list of supported options but still works in case anyone wants to use it.
