Pagerduty service can use 'source' as the incident key

[mheffner]

This is the use case:

In a scenario where you have many metrics across a set of common sources, an incident or outage on a single source can cause multiple metrics to simultaneously cross their configured alert thresholds. This can lead to an Pagerduty alert storm for a single incident on a single source. It would be preferable to collapse multiple Pagerduty alerts from the same source.

To support this we would need to have the option to use the source name as the Pagerduty incident_key. Simplest solution would be to have a boolean option that denoted "use source as incident key". That should address this use case.

@mheffner This would be a great solution for us. 👍

Plus one on this. It would be ideal to use the metric_name and source as the incident key. I think particularly with Librato set up for dynamic instruments and dashboards this is the bare minimum functionality for alerting.
