* Port publish-rlz pipeline to dronegen * Add artifact cleanup pipeline on tag, "before-all" * Bump relcli in all pipelines * Add missing license header * Refactoring to relcli steps per code review Only functionally-equivalent changes, .drone.yml identical to previous * Factor out relcli pipeline * Use docker:cli to pull relcli * Add "wait for docker" to relcli pipelines
