RetryScheduler. This default implementation checks if the last failure was transient, and if so reschedules a command dispatch.
commandMessage- The Command Message being dispatched
lastFailure- The last failure recorded for this command
failures- A condensed view of all known failures of this command. Each element in the array represents the cause of the element preceding it.
dispatchTask- the task that performs the actual dispatching.
