   ### Description of PR
   
   JIRA:https://issues.apache.org/jira/browse/HDFS-17657
   
   **Background**
   At present, the balance service supports long process deployment, but does 
not support web server services.
   
   **Implement functions**
   1.This PR mainly implements the basic capabilities of the web server, and 
through the UI interface, it can view metrics such as the amount of data 
currently being migrated by the balancer process, how much data the cluster 
still needs to migrate to reach balanced state, etc.
   
   2.Reuse the basic functions of HttpServer and HTML, support view conf, 
metrics, thread dump, etc.
