Allow some roles to edit Participant Custom Fields for the participant
Participant Custom Fields may contain information needed by others. For example, perhaps the review creator wants to have user x in a certain technical role (like "Requirements Engineer") in the review. Participant Custom Fields is great for this, except the review creator can't specify this. So, want to have participant custom fields editable by review creator and admins, and maybe a group of others (defined by a group) but I would be happy if the review creator, Moderator, and admin could set these for all participants to start.
