      • When a user creates a TempoStack from Tempo operator in a regular namespace, user can access the Tempo Jaeger Query console from: 

      Go to Networking → Routes and Ctrl+F to search for tempo.
      In the Location column, open the URL to access the Tempo console.
      Select Log In With OpenShift to use your cluster administrator credentials for the web console.

      • When a user creates a TempoStack in an OSSM SMMR member namespace, the Tempo Jaeger Query console is not accessible from the above Route.

      There is a requirement from OSSM side to provide an option of configuring Tracing without OTEL. In that case, a Tempo Stack must be created in a SMMR member namespace. Otherwise, istiod service registry cannot find the Tempo distributor svc host.
      We need a way of accessing Tempo jaegerQuery UI in the following how to produce steps:

      How to produce:

      • From an OCP cluster, install OSSM operator and Tempo operator
      • Create namespaces, "istio-system", "tracing-system"
      • Create a SMCP using the default CR yaml. For example,
      kind: ServiceMeshControlPlane
      apiVersion: maistra.io/v2
      metadata:
        name: basic
        namespace: istio-system
      spec:
        addons:
          grafana:
            enabled: false
          jaeger:
            install:
              storage:
                type: Memory
          kiali:
            enabled: false
          prometheus:
            enabled: false
        policy:
          type: Istiod
        telemetry:
          type: Istiod
        tracing:
          sampling: 10000
          type: None
        version: v2.4
      
      • Create a SMMR as below:
        kind: ServiceMeshMemberRoll
        apiVersion: maistra.io/v1
        metadata:
          name: default
          namespace: istio-system
        spec:
          members:
            - tracing-system
        
      • Create a Tempo Stack in namespace tracing-system
      • Verify all tempo pods are running and ready
      • Access the Tempo Jaeger Query console from: 
        Go to Networking → Routes and Ctrl+F to search for tempo.

      Current behavior: the route is not working.

      Expected behavior:
      Tempo should provide a queryFrontend access configuration other than the ingress.type: route. And user should be able to access jaegerQuery UI when a Tempo Stack in created in a SMMR member namespace
