Issue Summary

In Opsgenie, when responders are added to an incident, they can then be assigned a role - this allows others to immediately know who is responsible for what for the incident. 

See screenshot of behaviour in Opsgenie. 

Suggested Solution

Add "Responder Roles" to JSM incidents as well to bring feature parity from Opsgenie. 

Workaround

Create custom fields with responder roles and add them to the ticket. 

Once responders are added to the ticket, also update the custom field with the correct user.
