Description

When using telemetrygen to write traces over http, the --otlp-http-url-path defaults to /v1/metrics which is the path for metrics, not traces. When writing traces, it should default to the proper path.

Steps to Reproduce

Use telemetrygen to write traces to an http endpoint and do not specify a path

Actual Result

404 is thrown
