0.8 Python client

[David Arthur <mu...@gmail.com>]

Hello all,

I've been working on updating (i.e., rewriting) my Python client for the 
impending 0.8 release. Check it out:

https://github.com/mumrah/kafka-python/tree/0.8

In addition to 0.8 protocol support, the new client supports the 
broker-aware request routing required for replication in 0.8. Offset 
management is in there too, but disabled on the 0.8 branch since it will 
not be in that release. I believe it will be in a follow-on release 
(0.8.1, if JIRA can be believed).

TODOs:
* update unit tests for new protocol
* update queue.py with new producer/consumer stuff
* more tests
* more examples

I've been buried in the details of the protocol and request routing, so 
the actual useful API has had the least attention. I'm open to 
suggestions on how to make this library more useful/usable. And of 
course, pull requests are welcome!

Cheers,
David
