[kata-dev] Green CI Effort - All jobs as required

Hi all, As part of the Green CI Effort, we decided to put all the jobs that have a stable baseline as REQUIRED in order to merge a PR. The only job that I was not sure if it is stable or not is the kata-containers-2.0-ubuntu-20.04-ppc64le-main-baseline<http://jenkins.katacontainers.io/view/Daily%20baseline/job/kata-containers-2.0-ubuntu-20.04-ppc64le-main-baseline/>. If you have questions please let us know and if you see a CI that seems not stable enough please open a proper issue and assign it to the maintainer http://jenkins.katacontainers.io/view/Daily%20baseline/.
