cinder transfer-delete doesn't accept multiple transfers

[Rajat Dhasmana]

As most of the cinder resource delete commands support providing multiple resources, when we try to delete multiple transfers, we get the following error

$ cinder transfer-delete 257835ba-bb98-4765-9d4f-8708f0c7c8bd 75dd4297-354b-4964-99e0-01b64adefbd5
