Shlomi Noach 23cb8ea7e9 Throttling & critical load
- Added `--throttle-query` param (when returns > 0, throttling applies)
- Added `--critical-load`, similar to `--max-load` but implies panic and quit
- Recoded *-load as `LoadMap`
- More info on *-load throttle/panic
- `printStatus()` now gets printing heuristic. Always shows up on interactive `"status"`
- Fixed `change column` (aka rename) handling with quotes
- Removed legacy `mysqlbinlog` parser code
- Added tests
