ci/openshift-ci: Onboarding into the OpenShift CI

The OpenShift CI allows for components to be built and tested in clusters provided by the OpenShift community. This adds the minimum required on kata's side to get it onboarded in that CI system. More precisely, it introduces the buildall_install.sh script which is used to build and install kata-containers into a container image. Fixes kata-containers#2527 Signed-off-by: Wainer dos Santos Moschetta <[email protected]>
