Implementing configurable aggregation cardinality limit and collector emitting all views instead of last view

[PradSenn]

Fixes #3292
Cardinality of the Aggregation limit (2000) is hardcoded and no ability to configure as part of the meter/aggregation.

Meter stores meter-name to storage in storage_registry_. When multiple views are added, the last view overrides the previous view, and collector can only emit the last view's metrics that are added.

Changes

Please provide a brief description of the changes here.

Introducing cardinality as configurable parameter in AggregationConfig, and implementing the limit from AggregationConfig in Storage.

Changing the storage_registry_ to keep track of view_name to storage, instead of metric_name to storage. So when multiple views are added, different view-names will be collected by collector. Please provide a brief description of the changes here.
