improved scrubbing of oplogs and filecas (#596)

- Improvement: Scrub command now validates compressed buffer hashes in filecas storage (used for large chunks)
- Improvement: Added --dry, --no-gc and --no-cas options to zen scrub command
- Improvement: Implemented oplog scrubbing (previously was a no-op)
- Improvement: Implemented support for running scrubbint at startup with --scrub=<options>
