Make it easier on windows to install gcloud-python

Windows 10, MSVC 2015 installed. Python 3.4 (from python.org)

Right now when I tried to install gcloud-python using pip, it failed installing pycrypto. I found a binary installer for it and used that, but that's not optimal.

Here's the log from the install attempt:

C:\Python34\Scripts>pip install gcloud
You are using pip version 6.0.8, however version 7.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Thanks for reporting! We don't have much Windows expertise, so it's great to have people tell us what isn't working.

The binaries I used were here: http://www.voidspace.org.uk/python/modules.shtml#pycrypto
a SO search turned up this seemed to be one of the better ways (apart from installing an old MSVC) to get this working. After I installed this pycrypto binary package, then pip install gcloud-python worked.

@tseaver

@tseaver I've been toying around a bit and think we can drop pycrypto as a dep in setup.py.

We should chat. (Some evidence that hashlib MD5 is fast enough.)

FWIW, we use more than MD5:

$ git grep Crypto
gcloud/credentials.py:from Crypto.Hash import SHA256
gcloud/credentials.py:from Crypto.PublicKey import RSA
gcloud/credentials.py:from Crypto.Signature import PKCS1_v1_5
gcloud/credentials.py:    :rtype: :class:`Crypto.PublicKey.RSA._RSAobj`
gcloud/storage/_helpers.py:from Crypto.Hash import MD5

Yup. I ran the same git grep command but haven't figured out how to address yet (leaning towards dumping them into oauth2client). At least sha256 is included in hashlib.
