[SPARK-19185][DSTREAM] Make Kafka consumer cache configurable
## What changes were proposed in this pull request?
Add a new property `spark.streaming.kafka.consumer.cache.enabled` that
allows users to enable or disable the cache for Kafka consumers. This property
can be especially handy in cases where issues like SPARK-19185 get hit, for
which there isn't a solution committed yet. By default, the cache is still on,
so this change doesn't change any out-of-box behavior.
## How was this patch tested?
