Add option to return a submission with five or more recusals to the judging pool

[dboyer]

Depends on #5335 and #5336

Score monitors will review submissions with a high number of recusals and take one of three options:

1. Assign it to a specific judge (already a feature on the platform)
2. Unpublish it as a disqualified submission (already a feature on the platform)
3. Choose to return it to the judging pool

We need to support option 3. We shouldn't remove the recusals that are on the submission since we want to have that info tracked, but score monitors should have a button they can select to allow the submission to be in the judging pool even if it has 5 or more recusals.

Random thoughts/comments...

I wonder if having more complete admin functionality around this would be useful:

• Manually remove any submission from the judging pool
• Manually add any submission back to the judging pool
• A datagrid to view all submissions that have been removed from the judging pool

I think #5335 would just work in the background, behind the scenes, once a submission gets five recusals it would be automatically removed from the judging pool and be viewable on the new datagrid.
