Allow all contact modes to be used for "Incident Tracking"

[wleese]

It would be nice if any kind of contact mode could be used for incident tracking. Especially the ability to provide an arbitrary value is very nice.

Say for example you want to send all alerts to a chat room, but don't want to create user's that represent any random chat room your teams want to use. Incident tracking allows the user to select the channel (e.g. "chat") and type in the teams chat room they want to use for alerts (e.g. "Team 1a Alerts").
