Improving github workflow

[tbaranes]

It would be great to improve the github workflow:

• A better usage of labels to differentiate the issues, at least the basic ones if we don't create custom labels
• Using milestones to determinate which features should be implemented in the next version
• Something more?

Make this will definitely helps us to priorities and ease the development process.

Any thought?

I like the workflow, we can start with labels.

Closing this issue since the first step is done. We can reopen it later if we think it's not enough.
