[PATCH v4 09/13] Add trigger-test job, to run test on a Linux built from a branch/tag

[Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx>]

When scheduling pipeline in test-artifacts repo, it can get also
TEST_TRIGGER_REPO and TEST_TRIGGER_BRANCH variables, to trigger relevant
pipeline to test just built artifacts.
Pass ARTIFACTS_REPO+ARTIFACTS_BRANCH to the child pipeline to ensure it
fetches artifacts from the right job, but avoid xen test pipeline
inheriting other variables, as they might have unintended consequences
(for example REGISTRY one).
For example, to build linux-next and test Xen staging on it, the
pipeline could be triggered with:

    
LINUX_GIT_URL=https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
    LINUX_GIT_VERSION=master
    TEST_TRIGGER_REPO=xen-project/hardware/xen
    TEST_TRIGGER_BRANCH=staging

The triggered xen test pipeline will skip most build jobs.
