Tathagata Das 0a73aa31f4 [SPARK-23362][SS] Migrate Kafka Microbatch source to v2 
## What changes were proposed in this pull request?
Migrating KafkaSource (with data source v1) to KafkaMicroBatchReader (with data source v2).

Performance comparison:
In a unit test with in-process Kafka broker, I tested the read throughput of V1 and V2 using 20M records in a single partition. They were comparable.

## How was this patch tested?
Existing tests, few modified to be better tests than the existing ones.
