PRs should pass at least 1 peer review

[Malinskiy]

Right now anyone can merge changes without any peer feedback. I'd like to suggest to setup GH in a way that people are required to have at least 1 peer review (ideally 2).

Also, some form of CI that tests that docker images are created and are indeed working would be nice. Ideally with comparisons of image size and startup performance.

Thanks! Let me know if I can help you on how to achieve that with GH :)
