Must be completed BEFORE pushing to stage

If this is the first time we get a working set of images (e.g. z-stream), we also need to do a sanity check.

DoDs:

• Verify that the SHA of each “related_images” for each build attached to metadata Errata corresponds either to the builds attached to containers Errata or had been already released.
  You can use that script: check_builds_metadata.py
• Verify installations are completed
• Sanity check the UI making sure Kiali is showing the correct version for OSSM
• Install the latest SMCP. Look into Grafana UI and Verify that Istio dashboards show some data and the layout is correct (it doesn't overlap one over the other etc.). Reproducer for OSSM-6163
  • For 2.5.1, there is a known issue for 2 dashboards (OSSM-6267) ( please, remove this line once it is fixed )
