All sounds cool and doable.  But didn't we delete contrib/deploy in
favour of https://issues.apache.org/jira/browse/KAFKA-10 ?

I agree that something like https://github.com/pcmanus/ccm would be
useful for bringing up local clusters for local testing.

(And yeah, we should create a pid file instead of killing every running
