This replaces a map used as a set with a slice.
We were using a surprising amount of CPU in this code, making mapiters
to pull out a random element of the map. Instead, just rand.IntN to pick
a random element of the slice.
It also adds a benchmark:
│ before │ after │
│ sec/op │ sec/op vs base │
ConnRequestSet-8 1818.0n ± 0% 452.4n ± 0% -75.12% (p=0.000 n=10)
(whether random is a good policy is a bigger question, but this
optimizes the current policy without changing behavior)
