cannot find package "google.golang.org/grpc/transport"

Greetings! I am trying to start a grpcwebproxy, but when I try go get -u github.com/improbable-eng/grpc-web/go/grpcwebproxy i get:

root@f1b33891b086:/# go get -u github.com/improbable-eng/grpc-web/go/grpcwebproxy
package google.golang.org/grpc/transport: cannot find package "google.golang.org/grpc/transport" in any of:
	/usr/lib/go-1.10/src/google.golang.org/grpc/transport (from $GOROOT)
	/root/go/src/google.golang.org/grpc/transport (from $GOPATH)

I have the same result at MacOS and in ubuntu:latest docker image (so I guess it will be the minimum reproduction).

Full log with go get -u -v github.com/improbable-eng/grpc-web/go/grpcwebproxy

Ok, a workaround. Taking inspiration from some Docker code by @ryanjaeb, we can use git clone and dep instead of go get to make this work:

$ cd $GOPATH
$ mkdir src/github.com/improbable-eng
$ cd src/github.com/improbable-eng
$ git clone https://github.com/improbable-eng/grpc-web.git
$ cd grpc-web
$ dep ensure
$ cd go/grpcwebproxy
$ go install
$ echo "w00t!"

I’ve commandeered that PR since it’s so simple and I think we need it sooner rather than later, thanks for your attention to this matter @mrsmidge 😃.
