 * Query APIs (`CosmosClient::query_databases`, `DatabaseClient::query_containers`, `ContainerClient::query_items`) now return a `FeedPager` instead of an `azure_core::Pager`. The `FeedPager` type provides an abstraction over the transport layer, allowing for more flexibility when queries are executed over non-HTTP transports or are decoupled from specific HTTP responses (such as in cross-partition queries).
