Need to make sure msgpack-python version >= 0.4.0

[Feilong Wang]

Now we're depending on msgpack, but we didn't specify what version we're relaying on. However, Marconi code is using some new features introdcued [1,2,3] in msgpack 0.4.0, so if user are using the version under that, they may run into below error[4] and see HTTP 503 code.
