[BUG] 无法获取yaml格式的配置

[leoyox]

请简单描述bug的场景

如何重现

再现行为的步骤：

1. apollo创建yaml类型的namespace
2. 随便写点东西
3. 使用下面的代码访问并打印
4. 结果全部为空

x:
  y: true
  myName: false

package main
  2
  3 import (
    "fmt"
    //"strings"
    "github.com/apolloconfig/agollo/v4"
    "github.com/apolloconfig/agollo/v4/env/config"
    "github.com/apolloconfig/agollo/v4/extension"
    "github.com/apolloconfig/agollo/v4/utils/parse/yaml"
    "github.com/apolloconfig/agollo/v4/utils/parse/yml"
    "github.com/apolloconfig/agollo/v4/constant"
)
func init(){

    extension.AddFormatParser(constant.YAML, &yaml.Parser{})
    extension.AddFormatParser(constant.YML, &yml.Parser{})
}
func main() {
    c := &config.AppConfig{
        AppID:          "xxxx",
        Cluster:        "master",
        IP:             "xxxxx",
        NamespaceName:  "application,test.yaml",
    }

    //agollo.SetLogger(&DefaultLogger{})

    client, _ := agollo.StartWithConfig(func() (*config.AppConfig, error) {
        return c, nil
    })
    fmt.Println("初始化Apollo配置成功")
    x:=client.GetConfigCache("test.yaml")
    fmt.Println(x.Get("x.y"))
    fmt.Println(x.Get("x.myName"))
    fmt.Println(x.Get("x.myname"))
    fmt.Println(x)
    y:=client.GetConfig("test.yaml")
    fmt.Println(y.GetContent())
    fmt.Println(y.GetValue("x.myName"))
    fmt.Println(y.GetValue("x.myname"))
    fmt.Println(y.GetValueImmediately("x.myName"))
    fmt.Println(y.GetValueImmediately("x"))
    fmt.Println(y.GetStringValue("x.myName","xx"))
    fmt.Println(y.GetStringValue("x","yy"))
    fmt.Println(y.GetStringValue("x.myname","zz"))
}

可以直接运行下该部分代码

看起来对于yaml只能读取整个文本，不能获取诸如x.y.z

apollo 服务端实现上只有 properties 类型的配置支持 key value 读取，其他类型都是文本类型，配置文件的 key 为 content，建议可以自己实现 ChangeList，反解析到对应结构体即可。
