packer build failed because of UnknownBackupStorage

[qb0C80aE]

issue

When I tried to build machine image by packer-wakamevdc, an UnknownBackupStorage occured.
It said there was no backup storage named 'bkst-local', but I couldn't find any parameters about backup storage in related source files under wakame-vdc/client/.
My vdc has no backup storage named 'bkst-local'. It looks packer-builder-wakamevdc always tries to put image into 'bkst-local'.

log:

$ packer build packer-wakamevdc.json 
wakamevdc output will be in this color.

Build 'wakamevdc' errored: Error taking instance backup: API Error: Type: Dcmgr::Endpoints::Errors::UnknownBackupStorage, Code: 153, Message: bkst-local, (HTTP 404)

My backup storage setting is like below:

vdc-manage>> backupstorage show
UUID            Storage Type         Base URI            
bkst-demo1      local                file:///opt/axsh/wakame-vdc/images/
vdc-manage>> 

packer-wakamevdc.json:

{
  "builders": [
    {
      "type": "wakamevdc",
      "api_endpoint": "http://xxx.xxx.xxx.xxx:9001/api/12.03/",
      "image_id": "wmi-xxxx",
      "hypervisor": "kvm",
      "cpu_cores": 1,
      "memory_size": 512,
      "network_id": "nw-xxxx",
      "ssh_username": "root",
      "ssh_timeout": "60m"
    }
  ],
  "provisioners": [
    {
      "type": "shell",
      "inline": [
        "echo \"nameserver 8.8.8.8\" > /etc/resolve.conf",
        "yum update -y"
      ]
    }
  ]
}

fyi, It works almost fine after adding bkst-local.
(It still has an error of ssh key/security group deletion, though.)

I guess there should be the backup-storage-uuid parameter which is optional.
(or perhaps, is there that already? if so, sorry that I couldn't find.)

branch

packer-builder

[unakatsuo]

Since there was no parameter to set the upload destination, I have added new backup_storage_id conf parameter.

Also the fix for some resource cleanup issues are included.

f88814c is the new HEAD of packer-builder branch.
