Reduce VABC memory usage
BlockExtentWriter caches data in memory up until get gets a complete
extent. For full OTAs, extents are chopped to 2MB chunks. But for
incremental OTAs, extents can be as large as single file size. We have
observed a single extent to span >100MB disk space on pixel. This incurs
significant memory overhead depending on layout of file system image.
To reduce VABC memory usage, bound memory cache by 1MB
