Command-line interface for the `random` module

As far as I know many people prefer to remove flags for self-tests (1 2 3).
But in this module the flag --test is used for performance tests, maybe you can explain why it was added and whether anyone really uses it (or maybe we have a more convenient way)

As I wrote in the OP:

@hugovk

Currently, python -m random generates some sample test output. We could remove this, or if we still want it, move it to python -m random --test.

As I recall, no-one commented on this point either way, so I retained the sample output like this. I don’t think it’s really needed as we have unit tests.

But I suggest we close this old topic and open a new issue or topic if you want to remove --test.
