YAMAMOTO Takashi f39e95043c requirements: Drop some optional requirements 
Move some non pure python requirements (namely lxml and paramiko)
from pip-requires to test-requires.  Document it in README.rst.

Motivations:

- Make this pip-installable with pypy
- Less distribution package requirements (deb/rpm/etc) in case
  a user do not actually need the functionality

Note: while paramiko itself is pure python, it requires pycrypto.
Note: msgpack has pure python fallback implementation.

Separating ryu into smaller packages would be a better alternative.
However, it would involve a lot more work than this workaround.

% cd ryu; python ./setup.py install

If you want to use Ryu with OpenStack, please refer networking-ofagent project.

If you want to write your Ryu application, have a look at Writing ryu application document. After writing your application, just type:

% ryu-manager yourapp.py
