Improve our code comments to better leverage go docs and generate documentation from it

[knelasevero]

Describe the solution you'd like
Title says it. We can keep our interfaces/functions/structures/API easily documented by keeping our docs embedded to our code, exporting it from code comments with go docs.

What is the added value?
Contributors can focus on writing their code and already document it in only one go.

Give us examples of the outcome
