Thoughts on exposing uploadTraces/uploadMetrics?

[codeboten]

I was trying to translate metrics from Telegraf using the Otel Go SDK (https://github.com/influxdata/telegraf/pull/9109/files) and found myself re-using the grpc client in the opentelemetry-prometheus-sidecar (https://github.com/lightstep/opentelemetry-prometheus-sidecar/blob/main/otlp/client.go) instead of using the protocol driver.

I would be able to re-use the otlp grpc client code if uploadMetrics was available, as I already have a slice of ResourceMetrics. My question is whether there's a better way to go about this? Or if it would be possible to make that function available?

Either ways, I completely understand the API/SDK will change shortly so I guess what I'm looking for here is guidance from the community and wanted to provide this feedback.

This is definitely something that would be nice to enable. I think that the work @paivagustavo is doing on #1827 may enable this. Can you comment on that issue if you have any comments or concerns from this perspective?
