Commit Message

New tools, new option (#645)

- Add a new flatten command, which would flatten out all the LSM tree levels into a single level. It ensures that that level does not exceed its max size limits, as specified in the options.
- Add a new fill command, which would random key-values to Badger. Useful for testing.

## Option updates
- Add a new option to skip force compaction of Level 0 on DB.Close.
- Decrease the NumCompactors default value from 3 to 2.

Commits:

* Add two new commands: flatten and fill.
* Add an option to skip compacting Level 0 for performance reasons.
* Allow more compactors to run for flatten. Performance wise I didn't see any gains in latency while using multiple compactors. And there's a lot of resource consumption if multiple compactors are running concurrently. Could be due to all compactors working on the same level during flatten. In a live setting, compactors could be working on different levels, so the result might not directly apply.
* Decreased the NumCompactors default option to 2. Didn't set it to 1 to avoid a straggler compactor blocking all compactions.
* Add licenses.
