'cinder delete' should have an option to specify ID or NAME unambiguous otherwise wrong volume might be deleted if its ID is same with some other volume's NAME.

[shan-wan]

Description:

Currently 'cinder' command does not have any option associated with 'delete'.

$ cinder help delete
usage: cinder delete <volume> [<volume> ...]

Removes one or more volumes.

Positional arguments:
  <volume>  Name or ID of volume or volumes to delete.

It takes arguments as volume ID or volume NAME. This is OK for most cases.
But what if there're 2 such volumes, say: volume A has ID '1234' and volume B has NAME '1234' and 'cinder delete 1234' will delete volume A even if the user intends to delete volume B. This is ambiguous and 'cinder delete' should give an warning at least. It's better for 'cinder delete' to accept an option to specify '--id' or '--name'.
