Add an attachments API
This includes a new attachment controller and shell
commands. To use you'll need to set your api version
`export OS_VOLUME_API_VERSION=3.27`
Now you can do things like attach a volume (cinders part at least):
`cinder attachment-create --connect True ......`
List/show/delete existing attachments:
`cinder attachment-list`
`cinder attachment-show <attachment-id>`
`cinder attachment-delete <attachemnt-id>`
