[SPARK-6752][STREAMING][Revised] Allow StreamingContext to be recreated
from checkpoint and existing SparkContext
This is a revision of the earlier version (see #5773) that passed the
active SparkContext explicitly through a new set of Java and Scala API. The
drawbacks are.
* Hard to implement in python.
* New API introduced. This is even more confusing since we are introducing
getActiveOrCreate in SPARK-7553
Furthermore, there is now a direct way get an existing active SparkContext
or create a new on - SparkContext.getOrCreate(conf). Its better to use this to
get the SparkContext rather than have a new API to explicitly pass the context.
So in this PR I have
* Removed the new versions of StreamingContext.getOrCreate() which took
SparkContext
* Added the ability to pick up existing SparkContext when the
StreamingContext tries to create a SparkContext.
