Description

We have a number of reasons for task status updates, but we do not test all of them. On the other side, some failures that we check in our tests do not have reason field set. It would be nice to have a check for state, reason and source for every failed or lost task. E.g.

  AWAIT_READY(status4);
  EXPECT_EQ(TASK_LOST, status4.get().state());
  EXPECT_EQ(TaskStatus::SOURCE_SLAVE, status4.get().source());
  EXPECT_EQ(TaskStatus::REASON_EXECUTOR_TERMINATED, status4.get().reason());

To solve this problem several changes in different parts of the codebase should be made. Hence we make an epic out of it and do it step-by-step.
