Refactor Extension show and list command

1.keep the column display order consist in extension list with
  and without "--long" option.
2.rework for network extentsion list, openstacksdk return object,
  so the logic should be same with other service.
3.add some unit test cases, like: extension list --network --long,
  extension list --network --compute, to cover regular use cases.
4.raise exact exception when network extension don't exist, avoid
  internal TypeError in "extension show" commands.
