Add RuntimeDataFrame<T> and RuntimeDataFrameFactory<T> interface

[CaiJimmy]

This is to prepare for the iterator refactor, which will have a centralized logic of conversion between local, RDD and dataframe representation, and avoid duplicated codes.

public interface RuntimeDataFrame<T> extends Serializable {
    /**
     * Returns the underlying physical Spark DataFrame.
     */
    Dataset<Row> getDataFrame();

    /**
     * Converts this DataFrame to its logical runtime representation.
     *
     * @param metadata query metadata used if a row cannot be decoded
     * @return an RDD of logical runtime values
     */
    JavaRDD<T> toRDD(ExceptionMetadata metadata);
}
