Optimize the logic in org.apache.dubbo.common.URL#getEncodedServiceKey()

[ralf0131]

The currently implementation of org.apache.dubbo.common.URL#getEncodedServiceKey() is not elegant.

    public String getEncodedServiceKey() {
        String serviceKey = this.getServiceKey();
        serviceKey = serviceKey.replaceFirst("/", "*");
        return serviceKey;
    }

The purpose of replacing "/" with "*" is that Zookeeper does not support "/" as a valid character of key.

Proposal:

Add new parameter to getServiceKey(), for example: getServiceKey(String delimiter), and pass "/" or "*" in different scenario.

目前的实施org.apache.dubbo.common.URL#getEncodedServiceKey() 并不优雅。

    public  String getEncodedServiceKey（）{
         String serviceKey =  this 。getServiceKey（）; 
        serviceKey = serviceKey 。replaceFirst（“ / ”，“ * ”）;
        return serviceKey; 
    }

用“*”替换“/”的目的是Zookeeper不支持“/”作为密钥的有效字符。

提案：

添加新参数getServiceKey()，例如：getServiceKey(String delimiter)，并在不同的场景中传递“/”或“*”。

Do the different scenarios referred to here refer to different registration centers? I didn't understand what you mean.
