Description

After making access to ExecutionGraph single-threaded in FLINK-11417, we can simplify execution slot assignment in Execution.tryAssignResource and get rid of ASSIGNED_SLOT_UPDATER as it happens now only in one JM main thread. Though, it seems that we have to keep `assignedResource` as volatile at the moment which could be further investigated.
