OTLP exporters should set User-Agent header as per specification

[pichlermarc]

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

Currently the User-Agent header is not set by our exporters as defined in the specification.

Describe the solution you'd like

The User-Agent Header should be added as OTel OTLP Exporter JavaScript/<exporter version> in all OTLP exporters.

Additional context

Specification: https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/protocol/exporter.md#user-agent

Thanks!

@pichlermarc any update?

@dyladan No, not yet. I did not have time to work on that for a while. Also, it's not a single line change unfortunately.
I'll unassign myself for now in case someone has cycles and wants to pick it up.

Edit: I was not assigned. 😅 Added back the "up-for-grabs" label.
