Summary:
This adds:
1) use of --level_compaction_dynamic_level_bytes=true
2) use of --bytes_per_sync=2M
The second is a big win for disks. The first helps in general.
This also adds a new test, fillseq with 32kb values to increase the peak
ingest and make it more likely that storage limits throughput.
Sample outpout from the first 3 tests - https://gist.github.com/mdcallag/e793bd3038e367b05d6f
