Reconfigure Kafka defaults

- Set default number of partitions per topic -> 3. Helps ensure that out of the box we can take advantage of multi-node Kafka clusters via load balancing across atleast 3 brokers. Also multiple searchnodes will be able to pull from each topic. In this case 3 searchnodes (consumers) would be able to pull from all topics concurrently.
- Set default replication factor -> 2. This is the minimum value required for redundancy. Every partition will have 1 replica. In this case if we have 2 brokers each topic will have 3 partitions (load balanced across brokers) and each partition will have a replica on separate broker for redundancy
