Description
Set sending queue batch default values to match exporter helper default: flush timeout 200ms, min size 8192, no max size.
Context: when we applied the default batch values in #43419 to datadog-agent, we observed a regression in performance tests. Setting the batch values back to batch processor default values (also the exporter helper default) fixes the regression, thus this change.
A downside is if users ran into 413 payload too large errors, they now need to set the batch values in datadog::sending_queue::batch. This is reflected in the readme.
