Proposed title of this feature request

Export metrics in RHOSO via Service Exporters

What is the nature and description of the request?

[Please describe]

Why does the customer need this? (List the business requirements)

As an OpenStack RHOSO user, I want to be able to have the OpenStack services send metrics via a service exporter.  This will enable me to extend my RHOSO Observability to Partner enablements.  Also, this feature will enable me to use OpenTelemetry naming conventions in these metrics, allowing me to correlate signals more easily.
