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
fix:application/binary to application/octet-stream
fix: remove headers.copy()

These are removed on single block put operations, its however needed
in multi block post, to ensure that the headers are updated
everytime with the md5 of block being pushed into swift.
fix: validate if unpacked msgpack is dict

Also changes config.py to employ swift_testing section
for specifying information related to swift, and is no longer
dependent on the version of the swift driver
validation: check for msgpack content in request body

if not return a 400, with a comment saying Request Body
not well formed.
disable: pypy gate

We can also perhaps look at Eventlet for pypy support later.
fix: validation on POST v1.0/vaults/{vault}/blocks

We now make sure that we cant append anything to that endpoint,
otherwise we get back a 404 from validation.
add: dependencies to setup.py

Per Jorge's comment, we need dependencies in setup.py
fix: POST v1.0/vaults/{vault}/blocks endpoint

per Jorge's testing, we have make sure that request.body is called
with read() instead of getvalue()
