Thanks for this PR, @ludovicMercier!

Please allow me some time for proper review - it's a quite complex change.

Hi @jannfis,
I agree with you, take the time you need on the review.

@ludovicMercier I gave this PR some quick tests, and it worked great so far! I could even observe some performance improvements in contrast to using the (pretty old) docker-registry-client library.

I adapted my local checkout of your PR's branch to include latest changes in master branch, do you mind if I push them back to your PR's branch (or send a PR to your fork)?

I think it's good to merge, I just have a couple of tests in queue to perform either tomorrow or on the weekend.

Thank you! I really appreciate this contribution.

Hi @jannfis,
You can merge directly in this PR it's ok to me.
If i see someting else where i can help i'll rebase my fork to stay updated with the project.
