Fix: Fix bug in backoff calculations that would make Chao wait longer than it should after encountering API errors. This would lead to registered clusters disappearing and re-appearing in the Gremlin UI.
Info: Change maximum allowed max_backoff_duration from 10m to 4m. This is also the new default. Users specifying a longer backoff will see Chao agents fail to start as a result.
Info: Improved logging around API errors, removing large error outputs and other noise.
