Update for k6 org change

I now get this error when building my docker image:

I believe this is related to k6 moving off loadimpact to k6io?

Sorry for this, I've reverted the problematic commit in master, so this should now work.

To give some background, we merged #16 yesterday with the full expectation that we'll merge grafana/k6#1935 shortly after on the k6 side. But then we decided we'll not actually use github.com/k6io/k6 as the Go module path for k6, but Go for vanity URLs instead (e.g. something like go.k6.io/k6) and forgot to revert the xk6 change 😞

Btw you probably shouldn't use -u in go get, this is why it failed, you were using the master version that might be potentially unstable. And you shouldn't be using old versions of k6 unless you need to. I suggest you do something like this:

go install github.com/k6io/xk6/cmd/xk6@latest && xk6 build latest --with github.com/mostafa/xk6-kafka

This would make your Dockerfile use the latest stable versions of xk6 and k6.

@na-- Thanks for the quick response :) you're a life saver 🙏

On the topic of using versions to install a specific change, theres a small restriction on that.

With the above suggested code we aren't able to specify the version when using a path.. how unfortunate 🤕
package github.com/k6io/xk6/cmd/xk6@latest: cannot use path@version syntax in GOPATH mode

We will have to lock it a version and hope master is stable most of the time 🤞

You are using Go 1.15, that's why you see this error. Switch to Go 1.16 or add the GO111MODULE=on environment variable and the error should disappear.
