Support Snapshot backups

Creating a volume backup from a Snapshot, which is supported in v2, is not implemented yet.
It is already implemented and supported in the openstack CLI.

Example:

(openstack) volume backup create bf20730c-ddcb-4935-8b23-2ae7318bd274 --snapshot b4b3258d-555a-4fce-8f53-69cc2ae96d3c

POST a new backup including the snapshot

REQ:

$ curl -g -i -X \
  POST http://10.89.138.75:8776/v2/d1407d0e84e543a6a7ad9a31a5c65358/backups \
  -H "User-Agent: python-cinderclient" -H "Content-Type: application/json" \
  -H "Accept: application/json" -H "X-Auth-Token {SHA1}token" -d \
    '{
      "backup": {
        "force": false,
        "description": null,
        "snapshot_id": "b4b3258d-555a-4fce-8f53-69cc2ae96d3c",
        "incremental": false,
        "volume_id": "bf20730c-ddcb-4935-8b23-2ae7318bd274",
        "container": null,
        "name": null
      }
    }'

I will do a PR this weekend that will support snapshot backups using the implementation already introduced by @easyit.

[vinodborole]

thanks a lot @aiionx, appreciate your help here.

[daroay]

Thanks,

snapshot_id is still not documented at
http://developer.openstack.org/api-ref/block-storage/v3/?expanded=create-a-backup-detail

But anyways it is supported by the CLI and Openstack server... so I will include that.
And the force option too. Sometimes you want to backup even if the volume is attached, right?

Hi @aiionx,
Please close the issue if it's fixed.

[daroay]

Hi

@easyit opened the issue.
I came later.
So, I think I cant close it.
But indeed this is fixed by him and later I added a bit more.

Thanks.
