[SPARK-21236] Make the threshold of using HighlyCompressedStatus
configurable.
## What changes were proposed in this pull request?
Currently the threshold of using `HighlyCompressedMapStatus` is hardcoded
2000.
We could make this configurable. Thus users having enough memory on driver
can configure the threshold to be larger thus to save the size of blocks more
accurately in `CompressedMapStatus`.
