param `ControllerGetVolumeRequest` but it has no secret, so we cant use it for get volume

[yuclassic]

interface ControllerGetVolume has a GET param ControllerGetVolumeRequest. it has only 1 param volumeID, but it has no secret, then we can't use it for getting a volume.

did we have a TODO list for this improvement?

best wishes～
