     [SPARK-17631] [SQL] Add HttpStreamSink for structured streaming. Streaming 
query results can be sinked to http server

    ## What changes were proposed in this pull request?
    
    Add a class HttpStreamSink for structured streaming. This class extends 
StreamSinkProvider and DataSourceRegister. Streaming query results can be 
sinked to http server if we configure DataStreamWrite with 
.format("http").option("url", yourHttpUrl).
    e.g.
    
    val query = counts.writeStream
    .outputMode("append")
    .format("http")
    .option("url", "yourHttpUrl")
    .start()
    
    ## How was this patch tested?
    
    Use 
[quick-example](http://spark.apache.org/docs/latest/structured-streaming-programming-guide.html#quick-example)
 and configure DataStreamWriter with .format("http").option("url", yourHttpUrl)
