[SPARK-11419][STREAMING] Par recovery

The support for closing WriteAheadLog files after writes was just merged 
in. Closing every file after a write is a very expensive operation as it 
creates many small files on S3. It's not necessary to enable it on HDFS anyway.

However, when you have many small files on S3, recovery takes very long. In 
addition, files start stacking up pretty quickly, and deletes may not be able 
to keep up, therefore deletes can also be parallelized.

This PR adds support for the two parallelization steps mentioned above, in 
addition to a couple more failures I encountered during recovery. 

You can merge this pull request into a Git repository by running:

$ git pull https://github.com/brkyvz/spark par-recovery

Alternatively you can review and apply these changes as the patch at:
