Describe the solution you'd like

Integrate RuntimeComponent into servicemesh (redhat, istio)

maybe like:

apiVersion: rc.app.stacks/v1beta2
kind: RuntimeComponent
metadata:
  annotations:
    sidecar.istio.io/inject: "true"
  name: my-app
spec:
  applicationImage: quay.io/my-repo/my-app:1.0
  service:
    type: ClusterIP
    port: 9080
  expose: true
  servicemesh:
    enabled: true
    

then enroll RuntimeComponent's namespace in servicemesh via ServicemeshMember

and create service mesh resources for runtime component

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: <RuntimeComponent.Name>-gateway
  namespace: <RuntimeComponent.Namespace>
spec:
  selector:
    istio: ingressgateway # use istio default controller
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
      - <RuntimeComponent.Name>-<RuntimeComponent.Namespace>.<ClusterDomain>
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: <RuntimeComponent.Name>
  namespace: <RuntimeComponent.Namespace>
spec:
  hosts:
    -  <RuntimeComponent.Name>-<RuntimeComponent.Namespace>.<ClusterDomain>
  gateways:
  - <RuntimeComponent.Name>-gateway
  http:
  - name: <RuntimeComponent.Name>
    route:
    - destination:
        host: <RuntimeComponent.Servicename>
        port:
          number: <RuntimeComponent.Port>

more configuration options in RuntimeComponent Resource for Servicemesh should be discussed if needed, wanted, good to have
