Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/add-delete-on-termination-option.

Description:

There is the delete_on_termination option for attaching volume when creating a server but not for an existing server.

Attach a volume when creating a server, the API contains 'block_device_mapping', such as:
"block_device_mapping": [
            {
                "volume_id": "<VOLUME_ID>",
                "device_name": "/dev/vdc",
                "delete_on_termination": "true"
            }
]

It can contain 'delete_on_termination' option.

But attach a volume to existing server, there is no option 'delete_on_termination', the POST data likes:
{
    "volumeAttachment":{
    "volumeId":"<VOLUME_ID>",
    "device":"/dev/sdb"
    }
}
