Graceful VM Exits, Some Dials

Fly.io has introduced a new feature that allows users to delay VM shutdowns up to 24 hours, catering to applications with long-lived connections such as live video streaming services and database servers. This update enables users to specify the signal sent during shutdown and the time allowed for VMs to be kept alive after receiving the signal. The new feature aims to improve compatibility with various applications and reduce errors caused by abrupt terminations.
