Specific Slack channel notification per deployment

[skamoen]

Basically as described in #113, however that ticket was closed with only a separate approval feature.

I'd like to set channels for each deployment so that deployments for application-a sends notifications to a specific slack channel, and application-b to another.

Hi, sorry for closing that issue without completely resolving it.

It's a good idea to have an ability to override default channels by labels or annotations. I wonder what to do about Helm though, would this be configurable at chart or somewhere else. Nevertheless we could add labels or annotations to the event:

type EventNotification struct {
	Name      string       `json:"name"`
	Message   string       `json:"message"`
	CreatedAt time.Time    `json:"createdAt"`
	Type      Notification `json:"type"`
	Level     Level        `json:"level"`
        Labels map[string]string
}

And overwrite more than one thing.

@skamoen added this in #146, docs: https://keel.sh/v1/guide/documentation.html#Overriding-default-channels-per-deployment. Could you try it out and see whether this is something that you wanted?

Yes. This is perfect. Thanks a lot!
