[SPARK-17567][DOCS] Use valid url to Spark RDD paper

https://issues.apache.org/jira/browse/SPARK-17567 ## What changes were proposed in this pull request? Documentation (http://spark.apache.org/docs/latest/api/scala/#org.apache.spark.rdd.RDD) contains broken link to Spark paper (http://www.cs.berkeley.edu/~matei/papers/2012/nsdi_spark.pdf). I found it elsewhere (https://www.usenix.org/system/files/conference/nsdi12/nsdi12-final138.pdf) and I hope it is the same one. It should be uploaded to and linked from some Apache controlled storage, so it won't break again. ## How was this patch tested? Tested manually on local laptop. Author: Xin Ren <[email protected]> Closes apache#15121 from keypointt/SPARK-17567.

  * All of the scheduling and execution in Spark is done based on these methods, allowing each RDD
  * to implement its own way of computing itself. Indeed, users can implement custom RDDs (e.g. for
