Run qemu-coco-dev-runtime-rs k8s test workflow on the zVSI
only during nightly builds.
Changes:
- Split the zVSI k8s test workflow into two jobs in ci.yaml:
- Regular job: tests qemu, qemu-runtime-rs, qemu-coco-dev with
all snapshotters
- Nightly-only job: tests qemu-coco-dev-runtime-rs with nydus only
- Modified run-k8s-tests-on-zvsi.yaml to accept vmm and snapshotter
as workflow inputs instead of hardcoded matrix values
This ensures qemu-coco-dev-runtime-rs is only tested with nydus
snapshotter during nightly CI runs, reducing PR test time while
maintaining comprehensive nightly coverage.
