[SPARK-16953] Make requestTotalExecutors public Developer API to be consistent with requestExecutors/killExecutors

Browse source 
## What changes were proposed in this pull request?

RequestExecutors and killExecutor are public developer APIs for managing the number of executors allocated to the SparkContext. For consistency, requestTotalExecutors should also be a public Developer API, as it provides similar functionality. In fact, using requestTotalExecutors is more convenient that requestExecutors as the former is idempotent and the latter is not.
