kafka 0.8.2.2 release

[Richard Lee]

It appears from maven central and git that there was a 0.8.2.2 release 
on Sept 2nd.  However, the Kafka downloads page 
(https://kafka.apache.org/downloads.html) does not appear to have been 
updated.

Also, why aren't the kafka shell scripts made available as a .tgz file 
in maven central like they are for other apache projects (e.g. samza)?  
I would prefer to download a tarball from there and cache it in my 
company's local maven repo rather than have a special manual step to 
fetch them.
