Check campaign stage by submission
The same campaign could be submitted more than one time. We should be able to check a stage by the submission.
Detailed requirements from Pengfei:
The status checking should provide an additional option, letting the user to check:
1) all submissions for the campaign (if the user is using a draining dataset, and multiple submissions are only for recovery jobs, resulting in one file per parent file in the resulting POMS campaign for the next stage);
2) the last submission of the campaign (by default);
3) a previous submission.
