[chenjian88888]

The files from the following two paths have already been moved to 'modules/dreamview/backend/common,' the files in the original paths are no longer in use. However, they have not been deleted.

modules/dreamview/backend/map ----->modules/dreamview/backend/common/map_service modules/dreamview/backend/teleop ----->modules/dreamview/backend/common/teleop
