We have some tests that depend on random number generation, mainly for connection host failover. These tests were never really safely picking random numbers, they were inconsistent. I hacked some rand.Seed calls in to get it working, but never liked the solution.

With Go 1.25, rand.Seed doesn't work anymore and broke our main branch. I've skipped these tests for now (#1652) but we should look into updating to the new math/rand/v2 package.
