The last_seen_ts_threshold for getting alive executor at the scheduler side should be larger than the heartbeat time interval

Describe the bug
Currently the last_seen_ts_threshold for getting alive executor at the scheduler side is one minute. While the heartbeat between executor and scheduler is also 60 seconds. It will occasionally happen that alive executors fail to be detected due to hearbeat too late.
