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

0e7b23e6fe - Creating an populating Changelog table
- Using heartbeat
- Throttling works based on heartbeat
- Refactored binlog_reader stuff. Now streaming events (into golang channel, which makes for nice buffering and throttling)
- Binlog table listeners work
- More Migrator logic; existing logic for waiting on `state` events (e.g. `TablesCreatedState`)
