TrigCost: Change the first cost monitored algorithm from HLTSeeding to TrigCostSupervisor
After introducing the early cost monitoring we have to change the first cost monitored algorithm from HLTSeeding to TrigCostSupervisor. It is used for the event start timestamp. This algorithm has to be manually marked as started because it starts before the cost monitoring.
This issue caused a very long recorded HLTSeeding time - 1s average.
