This adds two goroutines to perform autopilot tasks on the leader - one to monitor the health of servers and another to periodically clean up dead servers with a limit on removal count. Also adds a new http endpoint, `/v1/operator/autopilot/health`, for querying this information through an operator RPC endpoint.
