Add conditions to Service and Binding CR to record the time when it becomes Online

[qibobo]

In other CRDs, there are conditions that can record when the CR is ready/online, and it is useful to measure how long it takes for the Service and Binding CR to be Online.

Below is an example for knative service:

status:
  address:
    url: http://knative-vcap.default.svc.cluster.local
  conditions:
  - lastTransitionTime: "2020-09-23T13:53:13Z"
    status: "True"
    type: ConfigurationsReady
  - lastTransitionTime: "2020-09-23T13:53:14Z"
    status: "True"
    type: Ready
  - lastTransitionTime: "2020-09-23T13:53:14Z"
    status: "True"
    type: RoutesReady

There is no such information for current Binding and Service.
