v1.16.2

Changes

• Add default config parameter, persistent_notifier_grouping, which controls how multiple notifications using the persistent_notifier for the same alert are handled. Can be "separate", "collapse" or "collapse_and_dismiss". "separate" will keep each notification distinct. "collapse" will result in a single persistent notification (keeping only the most recent notification). "collapse_and_dismiss" is similar to "collapse" except the notification is also dismissed if the alert is a condition alert and it turns off. Defaults to "separate".
