Refer to data model for delta and cumulative metric data points.
This is dependent on #1232 which implements Asynchronous storage.
Implement AsyncMetricStorage::Collect to fetch the delta metric data from the hashmap of aggregators and return it as a callback/ or span/list of metric data.
The aggregation-hashmap maintains the delta aggregation by default, which needs to be cleaned up after collection.
