Changes

job.yaml: fix apiVersion and other tweaks

The API version for templates is now `template.openshift.io/v1`.
Possibly `v1` was accepted before but not anymore? Fix it.

While we're here, tweak the template name to make it clearer that the
template itself is never created as an object.

Also remove the parameter default value to hard require clients to
always specify it.

buildconfig.json: fix apiVersion

The API version for templates is now `template.openshift.io/v1`.
Possibly `v1` was accepted before but not anymore? Fix it.

Missed doing this as part of badbfa0 ("job.yaml: fix apiVersion and
other tweaks").

kola/kolaTestIso: use `kola-junit` to publish JUnit test results

This will allow us to much more easily inspect failing kola tests.
Goes together with https://github.com/coreos/coreos-assembler/pull/3667,
which has more details.

While we're here, use `kola-testiso` as marker since it looks clearer
and for consistency with `kola-upgrade`.

pod: support setting env vars in the pod

We'll set NAME=VALUE for each requested environment variable.

cosaBuild: add `srcConfig` and `variant` parameters

I want to start building CentOS Stream CoreOS in CoreOS CI for at least
openshift/os and coreos/coreos-assembler.

Let's make it easier to point to a different source config than the
default FCOS.

vars/kola: deprecate --basic-qemu-scenarios

The argument for --basic-qemu-scenarios has been deprecated.
Depending on the version of cosa, the tests that would be skipped by these args are
now formal kola tests. And to skip them you can use --denylist-test commands.

skipSecureBoot now translates to  --denylist-test *.uefi-secure

vars/kola: Add support for skipping a list of kola tags

Introduce a kola parameter to allow skipping a list of kola tags.
This is particularly useful when adding new streams to the pipeline.
