use yaml or toml for conf file

[WLun001]

this is the current conf file, which I think very hard to read

<tars>
  <application>
    <server>
       #each adapter configuration 
       <TestApp.HelloServer.HelloObjAdapter>
            #allow Ip for white list.
            allow
            # ip and port to listen on  
            endpoint=tcp -h 10.120.129.226 -p 20001 -t 60000
            #handlegroup
            handlegroup=TestApp.HelloServer.HelloObjAdapter
            #max connection 
            maxconns=200000
            #portocol, only tars for now.
            protocol=tars
            #max capbility in handle queue.
            queuecap=10000
            #timeout in ms for the request in the queue.
            queuetimeout=60000
            #servant 
            servant=TestApp.HelloServer.HelloObj
            #threads in handle server side implement code. goroutine for golang.
            threads=5
       </TestApp.HelloServer.HelloObjAdapter>
    </server>
  </application>
</tars>

Proposed config file

server:
  TestApp.HelloServer.HelloObjAdapter: 
     allow: true
      ....

This configuration format is consistent with other language service frameworks, so it is not easy to change to yaml

unfortunately, these xml attributes are so hard to read
