feat(multiple block post): Swift and Disk

Deuce:
    POST v1/{vaultname}/blocks
        -Request body : msgpacked content of
                        dictionary of blockid
                        and blockdata
Swift:
    Asynchronous multiple block post
    py27 - gevent
    py33,34 - aiohttp and asyncio
            - lacks exception handling
Disk:
    Reference Driver
    Synchronous multiple block post
Q: Do we really need to have separate sections here?

At the very least, I think this would be improved by doing:
```
'swift': {
   'testing': {
       ...
   },
   'py2': {
      ...
   },
   'py3': {
      ...
   }
}
```

Though I still think we can just use 
```
'swift': {
   'testing': {
       ...
   },
  'driver': '...',
  'swift_module': '...'
}
```
And be just fine. Just put commented examples for Py2/Py3 in there. No need for separate sections.
