We need a page telling users how to add their workloads to the mesh. This will be an OSSM 3 equivalent content of this page: https://docs.openshift.com/container-platform/4.16/service_mesh/v2x/prepare-to-deploy-applications-ossm.html.

The content will be very different from OSSM 2, so this is high priority docs to include while in tech preview. Note that in OSSM 3, the ServiceMeshMember and ServiceMeshMember roll APIs are replaced by Istio's Discovery Selector feature.

• Topics to include:
  • namespace labels
  • pod labels
  • Manual sidecar injection (istioctl kube-inject if supported)
  • Verifying if a workload is included in the mesh
• Link to upstream doc as additional resource: https://istio.io/latest/docs/setup/additional-setup/sidecar-injection

Note: This issue was originally part of: https://issues.redhat.com/browse/OSSM-8200, and was split out.
