Add Impact and Urgency fields to 'View List Of Tickets' endpoint

Currently, freshservice’s API doesn’t offer impact and urgency fields in the ‘View List of Tickets’ API endpoint.  It’s odd since they offer them in the ‘View A Ticket’ endpoint.  Impact and urgency are required to properly establish a criticality for an incident ticket according to ITIL standards. . . . It’s odd that Freshservice would include them in one endpoint and not the other in the same endpoint hierarchy.  It seems more like a bug or design oversight than an enhancement . . . .
