Missing documentation about Spark's KuduContext API

      Description

      Right now there's no place to check the documentation about methods belonging to KuduContext.
      The only resources available only show some examples:
      https://kudu.apache.org/docs/developing.html#_spark_integration_best_practices

      Even when including the dependency in the IDE there are no documentation for each method.

      For example, I was getting a SparkException (which does not describe the actual error) when, accidentally, inserting rows in a table that already had the same rows. And the method insertRows from KuduContext does not mention that an exception can be thrown.
      Exception  example:

      18/12/05 11:26:35 ERROR core.JobRunShell: Job DEFAULT.EventKpisConsumer threw an unhandled Exception: 
      org.apache.spark.SparkException: Job aborted due to stage failure: Aborting TaskSet 109.0 because task 3 (partition 3) cannot run anywhere due to node and executor blacklist.  Blacklisting behavior can be configured via spark.blacklist.*.
