Special notes for your reviewer:

For now, this feature just affects outputs that use the outputs.Client.Post() or Put() methods.

Hey @ibice

Thank you for this PR. However, before we look at it, we need you to sign off your commits. Could you fix that, please? 🙏

Also, I've noticed some tests are falling, PTAL.

[ibice]

Done @leogr, I signed off the commits and solved the linter warnings :)
