Add a distinct virt-kdm AWS E2E job for KubeVirt Data Mover presubmits

[coderabbitai]

Summary

Create a distinct virtualized E2E CI job for KubeVirt Data Mover (KDM) validation.

The job name must contain virt-kdm. This name differentiates the KDM test from the existing general e2e-test-aws job in openshift/oadp-operator.

Rationale

The KDM controller and KDM plugin presubmits run the OADP operator E2E image with TEST_VIRT_KDM=true. This flag selects only the (kdm) Ginkgo-labeled specifications.

A distinct job name makes the selected suite explicit in CI results. It also prevents confusion with the general OADP operator virtualized E2E job.

Required changes

• Add or rename the OADP operator AWS virtualized KDM E2E job so that its name contains virt-kdm.
• Configure the job to run the KDM-only suite with TEST_VIRT_KDM=true.
• Keep the existing general e2e-test-aws job separate.
• Update the KDM controller and KDM plugin presubmit configuration to use the KDM-specific job.
• Apply the change for supported OADP release branches where the KDM presubmits run.
• Regenerate and validate the affected CI job definitions.

Acceptance criteria

• CI exposes a job name that contains virt-kdm.
• The job runs only (kdm)-labeled specifications.
• The KDM controller and KDM plugin presubmits use the virt-kdm job.
• The existing general e2e-test-aws job remains available and is not conflated with the KDM suite.
• Rehearsals confirm the KDM job executes the expected label filter and passes.
