Is your feature request related to a problem? Please describe.

exporterhelper can now be configured to partition the export data based on custom partitioner. The partitioner requires the new QueueBatchSettings. The partitioner can be defined based on the include_metadata_keys config and will be enabled with sending_queue::batch being defined.

NOTE that the partitioner is different from kafka partition.

Describe the solution you'd like

Migrate WithQueue to WithQueueBatch and define a custom Partitioner to partition export data by defined metadata keys.
