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

The Loki team at Grafana Labs was trying to identify the source of an anomaly on their backend and found out that it was related to how a specific tenant uses the Collector. It would have had been easier to identify this if we had a specific user-agent for requests going out from the Collector.

Therefore, this request is to set a specific user-agent for outgoing requests from the Loki exporter.

Describe the solution you'd like

The Loki exporter could set the user-agent on the HTTP client it uses to make the remote call.

This issue can be also beneficial to solve it in the OTLP HTTP exporter open-telemetry/opentelemetry-collector#8560
Thanks
