Pin go dependencies

We need to list and pin all the go dependencies.
With this we need to document their respective dependencies for Apache Software Foundation

This also helps a bit for stability

Could you look into this @sciabarra ?

I think is a matter of declaring them in build.gradle for gogradle to download them like the go CLI repo
