Add support for different notification channels for Deployments and Incidents

[YoranSys]

Currently, our notification system uses the same channel for all types of notifications, including deployment notifications and incident notifications. However, we would like to have the ability to use different channels for these two types of notifications.

For example, we would like to use a dedicated Slack channel for deployment notifications so that our development team can quickly see when a new deployment has been made and the impact of it.

On the other hand, we would like to use an other channel notifications for incidents, as this allows us to keep a more detailed record of incidents and enable notification alert.

Please let us know if there are any questions or concerns regarding this request.
