Change reporting from otel_collector to generic for the Otel Scenario

[wantsui]

Motivation

The reports are uploaded to the backend but @bojbrook found that the unexpected otel_collector type fails the update.

Changes

This goal of this change is to have a generic value for this field instead so @colin-higgins can make a more generic backend change.
