ResolveKey string
// Triggered is used to determine whether an alert has been triggered. When an alert is resolved, this value
// should be set back to false. It is used to prevent the same alert from going out twice.
//
// This value should only be modified if the provider.AlertProvider's Send function does not return an error for an
// alert that hasn't been triggered yet. This doubles as a lazy retry. The reason why this behavior isn't also
// applied for alerts that are already triggered and has become "healthy" again is to prevent a case where, for
// some reason, the alert provider always returns errors when trying to send the resolved notification
// (SendOnResolved).
