[Discussion]Java Chassis change all configuration from 'cse.xxx' to 'servicecomb.xxx'

[??????]

Hi ,all :
   we had support both style of configuration for a long time (since 0.2.0): 
https://github.com/apache/incubator-servicecomb-java-chassis/pull/91
   But all demos and samples in our code still use 'cse.xxx' such as :
  
 APPLICATION_ID: multiple
service_description:
  name: a-server
  version: 0.0.1
cse:                                                                  <------- 
old
  service:
    registry:
      address: http://127.0.0.1:30100
  rest:
    address: 0.0.0.0:8080
  highway:
    address: 0.0.0.0:7070
  
   I think it's time we may change all of them to 'servicecomb.xxx' like :
  
 APPLICATION_ID: multiple
service_description:
  name: a-server
  version: 0.0.1
servicecomb:                                                     <------- new
  service:
    registry:
      address: http://127.0.0.1:30100
  rest:
    address: 0.0.0.0:8080
  highway:
    address: 0.0.0.0:7070
  
  Any other ideas or suggestions are welcome !
