Optimizations have gotten my CI runs down from ~20 mins to ~8 mins

Mostly in build caching, but also in optimizing how many times the server actually has to boot to run the tests

The big bottleneck is still building the whole Vapor project on the CI runner to actually run the tests

I spend a lot of time talking product on here that sometimes I forget that playing with infra can be fun

I'll see about open sourcing this whole thing once it's launched

This is a fun project to really push @swiftlang and #ServerSideSwift
