v0.12.7 Alerting (new), enhancements, and bug fixes

Alerting

It's official. Cloudprober is getting its own alerting functionality 🎉. This release marks the beginning of the alerting implementation. We'll add more ways to notify an alert, but you can already trigger a command on alert. User documentation coming soon, but in the meantime, you can take a look at the alerting config proto to get an idea.
