Add Batch Limit for Stackdriver Exporter

[marvinkite]

On high-velocity metrics, you get:

InvalidArgument - Field timeSeries had an invalid value: A maximum of 200 TimeSeries can be written in a single request.

Apparently Stackdriver backend has the limit that each request cannot batch more than 200 time series so exporter needs to do some processing.

I have this issue with f0e0c76 commit

github.com/GoogleCloudPlatform/opentelemetry-operations-go/exporter/metric v0.34.3-0.20230106160205-f0e0c76a62e3

See GoogleCloudPlatform/opentelemetry-operations-js/issues/87

Thanks for reporting this! This is definitely something we need to implement. It exists on the googlecloud collector exporter for metrics, but not on the SDK exporter right now.

Would it be possible to get this ticket prioritized? I currently can't use the latest version of the exporter in production because it will constantly throw the maximum time series error. Thanks!

A naive implementation could be main...knightpp:opentelemetry-operations-go:issue-575.
