Check issue export status

This endpoint is used to poll for the progress of an issue export job and return the zip file after the job is complete. As long as the job is running, this will return a 202 response with in the response body a description of the current status.

After the job has been scheduled, but before it starts executing, the endpoint returns a 202 response with status ACCEPTED.

Once it starts running, it is a 202 response with status STARTED and progress filled.

After it is finished, it becomes a 200 response with status SUCCESS or FAILURE.
