Allow custom notes when service goes live

This adds an option on the organisation settings page to add
'request_to_go_live_notes'. When a service belonging to this
organisation requests to go live, any go live notes for the
organisation will be added to the Zendesk ticket in the 'Agreement
signed' section.
