Custom PHI lists at site/project level

[hkethi002]

Fixes #944

Changes From #877

• Project phi field (required field when creating project)
  • if project.phi == true, projects can have custom phi list
  • if phi is disabled for project, it is the same as if everyone has phi-access and modifying custom-phi lists is not allowed
• New collection of custom phi list for projects and site-level default
  • Project admins can set project level lists, site admins can set site-level lists
  • New ProjectSettings handler for custom-phi and project templates logic, rules are also in the same file
  • can only set phi fields that are PHI_CANDIDATES (this is a hardcoded list)
  • User can selectively choose subfields of the candidates
• New decorator to check phi-access for POST and PUT methods
• GET
  • get_all uses site level default phi fields
• If tags/notes are marked as PHI,
  • should a non-PHI user be able to add? - Yes
  • view? No
  • modify? - Yes for own notes, tags cannot be modified
  • delete? - Yes for own notes, no(?) for tags, but we'll allow for now.
• New AccessType modify-phi-list

ToDo

• Project phi field that enables phi functionality
• Subfields of PHI_CANDIDATES need to be permitted as phi fields
• Log changes made to custom phi lists
• Add more tests
• Redo the phi logic for list handlers (Notes and Tags)
