[Infra UI] Add new graphql endpoint for snapshot data (#34264)

* Add new graphql endpoint for snapshot data

* Polishing.

* Keep type generic that is used outside snapshots

* Keep one more generic type generic

* Use camelCase for consistency.

* Refine type names

* Add return types.

* Use idiomatic javascript.

* Factor out getAllCompositeAggregationData<T>()

* Refine naming.

* More idiomatic JavaScript, more types.
