Fix: addon name should not add prefix resources (#2808)

* Fix: addon name should not add prefix `resources`

- Adding prefix `resources will hit issues as:
'unable to parse requirement: invalid label value:
"resources-prometheus-server-register-grafana-datasource-5576f7f6b4":
      at key: "controller.oam.dev/component": must be no more than 63 characters'
- This won't avoid the name confliction with other components

* address comments
