> We should create an integration test to verify the proper behaviour of the slot allocation
protocol. The test should cover:
> * JM can allocate slots from the RM and receives the slot offers from the TM (regular
case)
> * RM can restore slot allocation after failure based on the {{SlotReport}} of the TMs
> * JM will retry slot allocation if RM failed to allocate slots
> * Crashed RM will re-allocate slots from RM and RM frees not recovered slots
> * TM failure is detected and JM allocates new slots from RM
> * JM and TMs continue working after successful slot allocation and failure of RM
