Update metadata visible to different roles
In the Control Panel and Review Screens, some of the visible information needs to be obscured from certain roles:
- Only admin should see the suggested and opposed editors
- Only admin, SE and HE should see the suggested/opposed reviewers, and the "Special instructions".
- Reviewers should not see anything past the yes/no metadata questions (hide from them suggested/opposed editors, suggested/opposed reviewers, and "Special instructions"
