Subject: [PATCH] Add test cases for consistent cache behavior

Using `rand.intn` test cases as template, we create similar tests
that verify consistent values returned by `uuid.rfc4122` and `time.now_ns`
builtins when invoked during the same evaluation/query.

These tests can also aid compliance regression testing for other OPA implementations,
such as Swift.
