Reusable meta-updater pipeline suiteBackport/rocko/secondaries

Squashed:

* Oe-selftest GitLab pipeline stage

* Use credentials for CI's oe-selftest

* Setup kvm trick for docker on CI

  The gid of the kvm group needs to match the one from the host

* Run ci scripts from Docker images

* Template out jobs and split .gitlab-ci.yml

  To be easily reused in other branches and projects

  Rely on this gitlab feature: https://docs.gitlab.com/ee/ci/yaml/#extends

* More flexible checkout script for CI

  - can work without $CURRENT_PROJECT (checks out everything)
  - can take a list of pinned versions

* Add optional CI jobs

  ptest and other oe-selftests

* Publish bitbaked images as artifacts
