Ingress中的property字段如何实现与社区client-go兼容？

使用场景

社区Ingress结构体中没有property属性，导致用户使用client-go调用创建ingress的api接口时，创建的Ingress中没有property属性。为了与社区的client-go兼容，CCE提供了如下解决方案。

解决方案

在使用client-go创建Ingress实例时，在annotation中做如下声明：

kubernetes.io/ingress.property: '[{"host":"test.com","path":"/test","matchmode":"STARTS_WITH"},{"host":"test.com","path":"/dw","matchmode":"EQUAL_TO"}]'

匹配规则：用户调用CCE的Kubernetes接口创建Ingress时，会试图匹配Ingress rules中的host和path两个字段，如果和annotation中的host和path一致，则会在这条path下面注入property属性，示例如下：

kind: Ingress
apiVersion: extensions/v1beta1
metadata:
  name: test
  namespace: default
  resourceVersion: '2904229'
  generation: 1
  labels:
    isExternal: 'true'
    zone: data
  annotations:
    kubernetes.io/ingress.class: cce
    kubernetes.io/ingress.property: '[{"host":"test.com","path":"/test","matchmode":"STARTS_WITH"},{"Path":"/dw","MatchMode":"EQUAL_TO"}]'
spec:
  rules:
     - host: test.com
       http:
        paths:
          - path: /ss
            backend:
              serviceName: zlh-test
              servicePort: 80
          - path: /dw
            backend:
              serviceName: zlh-test
              servicePort: 80

转换后的格式如下：

kind: Ingress
apiVersion: extensions/v1beta1
metadata:
  name: test
  namespace: default
  resourceVersion: '2904229'
  generation: 1
  labels:
    isExternal: 'true'
    zone: data
  annotations:
    kubernetes.io/ingress.class: cce
    kubernetes.io/ingress.property: '[{"host":"test.com","path":"/ss","matchmode":"STARTS_WITH"},{"host":"","path":"/dw","matchmode":"EQUAL_TO"}]'
spec:
  rules:
     - host: test.com
       http:
        paths:
          - path: /ss
            backend:
              serviceName: zlh-test
              servicePort: 80
            property:
              ingress.beta.kubernetes.io/url-match-mode: STARTS_WITH
          - path: /dw
            backend:
              serviceName: zlh-test
              servicePort: 80
