It's way simpler. It exerceises the same features of remote helpers.
It's easy to read and understand. It doesn't depend on python.

It does _not_ exercise the python remote helper framework; there's
another tool and another test for that.

For now let's just copy the old remote-helpers test script, although
some of those tests don't make sense for this testgit (they still pass).

In addition, this script would be able to test other features not
currently being tested.
