discovery: new devel.discovery.randomize option

By default, this is True, but setting it to False is a uniform
way to kill all randomness in integration tests such as test-setdiscovery.t

By "uniform" we mean that it can be passed to implementations in other
languages, for which the monkey-patching of random.sample would be
irrelevant.

In the above mentioned test file, we use it right away,
replacing the adhoc extension that had the same purpose, and to derandomize a
case with many round-trips, that we'll need to behave uniformly in the Rust
version.
