Tathagata Das 0a078303d0 [SPARK-9556] [SPARK-9619] [SPARK-9624] [STREAMING] Make BlockGenerator more robust and make all BlockGenerators subscribe to rate limit updates ... In some receivers, instead of using the default `BlockGenerator` in `ReceiverSupervisorImpl`, custom generator with their custom listeners are used for reliability (see [`ReliableKafkaReceiver`](https://github.com/apache/spark/blob/master/external/kafka/src/main/scala/org/apache/spark/streaming/kafka/ReliableKafkaReceiver.scala#L99) and [updated `KinesisReceiver`](https://github.com/apache/spark/pull/7825/files)). These custom generators do not receive rate updates. This PR modifies the code to allow custom `BlockGenerator`s to be created through the `ReceiverSupervisorImpl` so that they can be kept track and rate updates can be applied. In the process, I did some simplification, and de-flaki-fication of some rate controller related tests. In particular. - Renamed `Receiver.executor` to `Receiver.supervisor` (to match `ReceiverSupervisor`) - Made `RateControllerSuite` faster (by increasing batch interval) and less flaky - Changed a few internal API to return the current rate of block generators as Long instead of Option\[Long\] (was inconsistent at places). - Updated existing `ReceiverTrackerSuite` to test that custom block generators get rate updates as well.
