I'm working on adapting the CI to the new operator package... I'm testing it in my fork and will push the changes here once I get a green build.

@jakubschwan if you have time to check some baselines, let me know. I am currently struggling with local environment setup :D

great job.. quite an effort as this PR shows that was not only move files, but not only adapt internal dependencies but also have to change the CI to accommodate larger builds (nice partitioning strategy!)

looks good
