Build docker images based on Red Hat UBI (elastic#20576)
Add an additional docker build that builds images based on Red Hat UBI, following Red Hat requirements for certified images. Additional checks have been added to packaging tests for labels and licenses. Additional changes done to support it also in Elastic Agent images: * Home directory is prepared in a different stage (elastic#20356). * Allow the docker image to be run with random user ids (elastic#18873). * Explicitly select a Dockerfile and entry point template. * Add NOTICE.txt file to all agent packages. * Actually run package tests after building packages, added flag to allow root user. * Improved checks on required packages, so they are not re-built if they already are.
