[SPARK-12411] [CORE] Decrease executor heartbeat timeout to match heartbeat
interval
Previously, the rpc timeout was the default network timeout, which is the
same value
the driver uses to determine dead executors. This means if there is a
network issue,
the executor is determined dead after one heartbeat attempt. There is a
separate config
for the heartbeat interval which is a better value to use for the heartbeat
RPC. With
this change, the executor will make multiple heartbeat attempts even with
RPC issues.
