Fix job submission progress percentage

Summary:
The sqoop2 client's 'submission status --jid N' command misreports the true progress. Eg, reports 0.50% instead of 50%.

Details:
I submitted a job and looked at the web link page. I saw that point that the map phase was 100% complete and the reduce phase had not yet started. So I expected to see '50%' progress back in the sqoop2 client's 'submission status --jid N' output. But instead of 50%, I see 0.50%:

sqoop:000> submission status --jid 3
