The currently supported states are:
* not-started - Has yet to start. If in this state, a transfer
can be canceled immediately and nothing will happen.
* queued - SubmissionTask is about to submit tasks
* running - Is inprogress. In-progress as of now means that
the SubmissionTask that runs the transfer is being executed. So
there is no guarantee any transfer requests had been made to
S3 if this state is reached.
* cancelled - Was cancelled
* failed - An exception other than CancelledError was thrown
* success - No exceptions were thrown and is done.

result because it is invoked on the final task where there is only
ever one final task and it is ran at the very end of a transfer
process. So if a result is being set for this final task, the transfer
succeeded even if something came a long and canceled the transfer
on the final task.
