This is similar to #5999, but for streaming. Roughly 200 lines are tests.
One thing to note here is that we already do some kind of scoping thing for call sites, so this patch adds the new RDD operation scoping logic in the same place. Also, this patch adds a `try finally` block to set the relevant variables in a safer way.

Learnt a lesson from SPARK-7655: Spark should avoid to use `scala.concurrent.ExecutionContext.Implicits.global` because the user may submit blocking actions to `scala.concurrent.ExecutionContext.Implicits.global` and exhaust all threads in it. This could crash Spark. So Spark should always use its own thread pools for safety.
This PR removes all usages of `scala.concurrent.ExecutionContext.Implicits.global` and uses proper thread pools to replace them.

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.

In a REPL/notebook environment, its very easy to lose a reference to a StreamingContext by overriding the variable name. So if you happen to execute the following commands
```
val ssc = new StreamingContext(...) // cmd 1
ssc.start() // cmd 2
...
val ssc = new StreamingContext(...) // accidentally run cmd 1 again
```
The value of ssc will be overwritten. Now you can neither start the new context (as only one context can be started), nor stop the previous context (as the reference is lost).
Hence its best to maintain a singleton reference to the active context, so that we never loose reference for the active context.
Since this problem occurs useful in REPL environments, its best to add this as an Experimental support in the Scala API only so that it can be used in Scala REPLs and notebooks.

The problem most likely resides in DStream.slice() implementation, as shown below.
def slice(fromTime: Time, toTime: Time): Seq[RDD[T]] = {
if (!isInitialized) {
throw new SparkException(this + " has not been initialized")
}
if (!(fromTime - zeroTime).isMultipleOf(slideDuration)) {
logWarning("fromTime (" + fromTime + ") is not a multiple of slideDuration ("
+ slideDuration + ")")
}
if (!(toTime - zeroTime).isMultipleOf(slideDuration)) {
logWarning("toTime (" + fromTime + ") is not a multiple of slideDuration ("
+ slideDuration + ")")
}
val alignedToTime = toTime.floor(slideDuration, zeroTime)
val alignedFromTime = fromTime.floor(slideDuration, zeroTime)
logInfo("Slicing from " + fromTime + " to " + toTime +
" (aligned to " + alignedFromTime + " and " + alignedToTime + ")")
alignedFromTime.to(alignedToTime, slideDuration).flatMap(time => {
if (time >= zeroTime) getOrCompute(time) else None
})
}
Here after performing floor() on both fromTime and toTime, the result (alignedFromTime - zeroTime) and (alignedToTime - zeroTime) may no longer be multiple of the slidingDuration, thus making isTimeValid() check failed for all the remaining computation.
The fix is to add a new floor() function in Time.scala to respect the zeroTime while performing the floor :
def floor(that: Duration, zeroTime: Time): Time = {
val t = that.milliseconds
new Time(((this.millis - zeroTime.milliseconds) / t) * t + zeroTime.milliseconds)
}
And then change the DStream.slice to call this new floor function by passing in its zeroTime.
val alignedToTime = toTime.floor(slideDuration, zeroTime)
val alignedFromTime = fromTime.floor(slideDuration, zeroTime)
This way the alignedToTime and alignedFromTime are *really* aligned in respect to zeroTime whose value is not really a 0.

In environments like notebooks, the SparkContext is managed by the underlying infrastructure and it is expected that the SparkContext will not be stopped. However, StreamingContext.stop() calls SparkContext.stop() as a non-intuitive side-effect. This PR adds a configuration in SparkConf that sets the default StreamingContext stop behavior. It should be such that the existing behavior does not change for existing users.

The original codes didn't have a memory barrier in the `eventually` closure, which might fail the test, because JVM doesn't guarantee the memory consistency between different threads without a memory barrier.
This PR used `ConcurrentLinkedQueue` to set up the memory barrier.

Users may want the WAL data to be written to non-HDFS data storage systems. To allow that, we have to make the WAL pluggable. The following design doc outlines the plan.

This is to ensure that receivers that receive data in small batches (like Kinesis) and want to add them but want the callback function to be called only once. This is for internal use only for improvement to Kinesis Receiver that we are planning to do.

Currently if you want to create a StreamingContext from checkpoint information, the system will create a new SparkContext. This prevent StreamingContext to be recreated from checkpoints in managed environments where SparkContext is precreated.
The solution in this PR: Introduce the following methods on StreamingContext
1. `new StreamingContext(checkpointDirectory, sparkContext)`
Recreate StreamingContext from checkpoint using the provided SparkContext
2. `StreamingContext.getOrCreate(checkpointDirectory, sparkContext, createFunction: SparkContext => StreamingContext)`
If checkpoint file exists, then recreate StreamingContext using the provided SparkContext (that is, call 1.), else create StreamingContext using the provided createFunction
