Dependency on "testing" from "google.golang.org/grpc/experimental/stats" about grpc-go HOT 4 OPEN

To add a bit more color here, in our repo we check for unexpected dependencies of our binaries. This is done to reduce binary bloat, to avoid side effects of those dependencies (eg. importing "testing" use to register flags that are exposed by the final binary, but this is no longer the case), and just generally to have a cleaner dependency tree.

A dependency we disallow in production binaries is "testing", which is how we noticed that grpc started depending on it.

@aaronbee : Thanks for filing this issue. How do you check for unexpected dependencies of your binaries in your repo? Is that something that you can share with us?

We have a small program (that's not open source, sorry) that uses golang.org/x/tools/go/packages to load a package and walk its dependency tree, reporting any uses of forbidden dependencies. Another simple way to this is with go list -deps which will just print out all the dependencies of a package.
