plugin: envoyplugin support wasm/rider

[YonkaFang]

使用方式如下：

# namespace: ns1
  - enable: true
    name: fault-injection
    rider:
      settings:
        delay:
          delaySwitch: true
          delayTime: 3000
        error:
          errorSwitch: false
    typeUrl: type.googleapis.com/proxy.filters.http.rider.v3alpha1.RouteFilterConfig
  - enable: true
    name: fault-injection
    typeUrl: type.googleapis.com/envoy.extensions.filters.http.wasm.v3.RoutePluginConfig
    wasm:
      settings:
        blockRules:
        - .*
        caseInsensitive: false
        rejectedCode: "422"

输出envoyfilter如下：

  - applyTo: HTTP_ROUTE
    match:
      context: SIDECAR_OUTBOUND
      routeConfiguration:
        vhost:
          name: nsf-demo-stock-viewer-sidecar.skiff-nsfdemo-sidecar.svc.cluster.local:80
          route:
            name: myroute
    patch:
      operation: MERGE
      value:
        typedPerFilterConfig:
          ns1.fault-injection.rider:
            '@type': type.googleapis.com/udpa.type.v1.TypedStruct
            type_url: type.googleapis.com/proxy.filters.http.rider.v3alpha1.RouteFilterConfig
            value:
              plugins:
              - config:
                  delay:
                    delaySwitch: true
                    delayTime: 3000
                  error:
                    errorSwitch: false
                name: fault-injection
  - applyTo: HTTP_ROUTE
    match:

          route:
            name: myroute
    patch:
      operation: MERGE
      value:
        typedPerFilterConfig:
          ns1.fault-injection:
