Verified Addon promotion rules

If this pr wants to promote an experimental addon to verified, you must check whether meet these conditions too:

• This addon must be tested by addon's e2e-test to guarantee this addon can be enabled successfully.
• This addon must have some basic but necessary information.
  • An accessible icon url and source url defined in addon's metadata.yaml.
  • A detail introduction include a basic example about how to use and what's the benefit of this addon in README.md.
  • Also provide an introduction in KubeVela documentation.
  • It's more likely to be accepted if useful examples provided in example dir.

BTW, can we use different ways except port-forward? Such as nodeport/ingress/slb.

@wonderflow, The CRD was outdated that I was installing before, these're current version's CRDs.

@wonderflow Off-course we can use diffrent ways than port-forward, but fot that I'll have to create addtional services as all the services that're by default created of type ClusterIP.

We should provide some ways for it in Application yaml examples, we can add some traits like expose/gateway. Users need to learn how this can work in their real world case. No one can use port-forward for develop or production environment long except demo.

@wonderflow I've created some custom traits to expose nodeport services. Please review that :)
