Automate TC 28597 : Telemetry info on migration

[hu-weihua]

This is automatic test case for TC28597

This test case is used to test CAM and Prometheus integration. Customer can leverage this feature to have better visibility on how successful when migrating their applications.

After deploying CAM (version >=1.1.2),
The steps of TC28597 are

• Add label openshift.io/cluster-monitoring: "true" to namespace openshift-migration
• Check if service/mig-controller-metrics is running
• Check if metrics can be expose from API http://mig-controller-metrics.openshift-migration.svc.cluster.local:2112/metrics
• Check if can query metrics from OCP monitoring prometheus web console. this step won't be covered by automation.

@hu-weihua @sergiordlr Can we rebase this one? Do we want this test on the upstream CI batch? We need to implement a way to discriminate tests only for a single CAM release based on tags otherwise some jobs might attempt and fail on older releases, this is on me.

@fbladilo I have remove the role of this case from e2e_mig_samples.yml.
I think it won't impact CI test. But in QE team internal test. we can use this one.
What do you think?
