Etcd: Can't install etcd/tools/benchmark via go get

[Cjen1]

Using go get go.etcd.io/etcd/tools/benchmark results in:

go/src/go.etcd.io/etcd/vendor/google.golang.org/grpc/balancer_conn_wrappers.go:28:2: use of internal package google.golang.org/grpc/internal/buffer not allowed 
go/src/go.etcd.io/etcd/vendor/google.golang.org/grpc/clientconn.go:49:2: use of internal package google.golang.org/grpc/internal/resolver/dns not allowed
go/src/go.etcd.io/etcd/vendor/google.golang.org/grpc/clientconn.go:50:2: use of internal package google.golang.org/grpc/internal/resolver/passthrough not allowed

This has worked previously and is running on go version go1.11.5 linux/amd64

This command does work however on go version go1.10.4 linux/amd64

@Cjen1 can you also please try the latest supported go 1.13 and see how that goes? Thanks!

[Cjen1]

Hi trying on go version go1.13.6 linux/amd64 fails with the same error. I've gotten around this by cloning the repo locally and then using go build && go install and that has appeared to work, it is just the go get version which fails.

@Cjen1 thanks for verifying. I think the error is due to the vendor directory is missing the referenced internal packages. I am digging into it more and will work on fix. Thanks!

@Cjen1 This is fixed under https://github.com/etcd-io/etcd/pull/11557 I am closing the issue after successfully running the go get. Please reopen if needed. Thanks!
