James Tucker	eca5b33a78	tstest: add a helper for reproducable random seeds We recently ran across a case of flaky tests that were seeding the math/rand package and using that to generate data. The tests were flaking on specific random values that were difficult to reproduce. If the test had been using a helper like this, the flaky cases could have been reliably reproduced.

tstest: add a helper for reproducable random seeds

We recently ran across a case of flaky tests that were seeding the
math/rand package and using that to generate data. The tests were
flaking on specific random values that were difficult to reproduce. If
the test had been using a helper like this, the flaky cases could have
been reliably reproduced.

tstest: add method to Replace values for tests

We have many function pointers that we replace for the duration of test and
restore it on test completion, add method to do that.
