[SPARKR][SPARK-8742] Improve SparkR error messages for DataFrame API
This patch improves SparkR error message reporting, especially with
DataFrame API. When there is a user error (e.g., malformed SQL query), the
message of the cause is sent back through the RPC and the R client reads it and
returns it back to user.
