      Description

      I have a job in state RESTARTING. When I now issue a cancel RPC call, I get the following exception:

      Relevant trace:

      (Sorry for the poor stack trace formatting, I coped the stack trace from the UI)

      It seems that the Canceling state assumes we only transition into it from Executing (ExecutionGraph = RUNNING).

      In my opinion a job should be cancellable at all times, for example when a job is stuck in a restart loop, cancelling is the only way out (unless retries are exhausted).
