The tasks associated with a VM originally could exit with an error on startup, and we'd retry after a duration. This hasn't been possible for some time, so we're better off removing the machinery for it.
Note: This PR removes the following metric:
autoscaling_agent_runner_fatal_errors_total
Notes for review: Given the metric is currently always zero, we should preemptively remove it from dashboards & alerts before merging.
Also worth noting this came up as part of neondatabase/docs#96.
