DS-1945 New override property request.item.helpdesk.override to have all email requests sent to the helpdesk instead of the item submitter
DS-1945 refactor to move code into dspace-api

Cleans up Sam's "hard coded" approach
DS-1945 RequestItem Helpdesk has options to contact requester, and author
DS-1945 Add request_message to requestitem DB table

Also, refactored requestitem to be a dspace-api "model", moved all DB logic

Add the requestitem.request_message to display in the contact-author form,
so they can see what the original request message was.
