Revision Tags Prologue

Now, the updated mapping between revisions, tags, and namespaces is as shown below:

{{< image width="90%" link="/docs/setup/upgrade/canary/revision-tags-after.svg" caption="Namespace labels unchanged but now all namespaces pointed to {{< istio_full_version_revision >}}"

}}

Restarting injected workloads in the namespaces marked prod-stable will now result in those workloads using the {{< istio_full_version_revision >}} control plane. Notice that no namespace relabeling was required to migrate workloads to the new revision.
