Kafka Partition Availability Benchmark

I wrote the initial version of this tool in order to stress Kafka when you create a large number of topics. It used to validate KIP-227, which helped remove a major performance impediment to Kafka if you added more than around 50K topic partitions.

We found this tool useful as our Kafka monitor at Lyft. Due to CLA conflicts, we had to run our own fork at Lyft for this: https://github.com/lyft/kafka-partition-availability-benchmark The latter fork is the most recent and up-to-date code. My colleague and I used it to create our demo for our Kafka Summit talk.
