      Description

      We want to change the default percentage to 100 for spark.shuffle.server.chunkFetchHandlerThreadsPercent. The reason being
      currently this is set to 0. Which means currently if server.ioThreads > 0, the default number of threads would be 2 * #cores instead of server.io.Threads. We want the default to server.io.Threads in case this is not set at all. Also here a default of 0 would also mean 2 * #cores
