[samobermiller]

• Reviewer for a submission now has access to a drop down menu with limited status transitions
  • all status transitions are limited by user's role (admin, reviewer or owner) and the submission's current Status
  • all available status transitions are laid out in a single dictionary accessed via api (per pk suggestion)
  • reviewer has been added as a permission_level in the backend code
  • list of reviewer and contributor (owners, editors and metadata contributors) orcids now available on record object to use in frontend, to inform whether user sees Resume or View for each submission and to inform whether user sees a drop down menu for a submission
