[Fine-grained recovery task-level] In a vertex, task 0 is done task 1 is running. History flush happens. AM dies. Once AM is recovered, task 0 is not re-run. Task 1 is re-run.
[Data movement types] Test AM recovery with all data movement types including 1-1, broadcast, scatter-gather with/without shuffle. AM should die in 2 scenarios: first-vertex task finishes completely and partially.
[Kill AM many times] Set AM max attempt to high number. Kill many attempts. Last AM can still be recovered with latest AM history data.
