This is in its own separate package so that it will be a separate test binary that runs thus isolating the go runtime from other tests and allowing accurate go routine leak checking.
This test would ideally use goleak.VerifyTestMain but that will fail 100% of the time due to some architectural things (blocking queries and net/rpc uncancellability).
This test is not comprehensive. We should enable/exercise more features and more cluster configurations. However its a start.
- You can no longer cross submodule boundaries with ./... in go
subcommands like `go list` or `go test`. The makefile and CI scripts
were updated accordingly.
- Also of note: `go mod vendor` now omits things build ignored.
