[SPARK-13845][CORE] Using onBlockUpdated to replace onTaskEnd avioding driver OOM

## What changes were proposed in this pull request?

We have a streaming job using `FlumePollInputStream` always driver OOM after few days, here is some driver heap dump before OOM

```
`BlockStatus` and `StreamBlockId` keep on growing, and the driver OOM in the end.
After investigated, i found the `executorIdToStorageStatus` in `StorageStatusListener` seems never remove the blocks from `StorageStatus`.
In order to fix the issue, i try to use `onBlockUpdated` replace `onTaskEnd ` , so we can update the block informations(add blocks, drop the block from memory to disk and delete the blocks) in time.

## How was this patch tested?

Existing unit tests and manual tests
