Please describe the feature request.
The idea is to make it available for any consumer of the micrometer-otlp-registry to provide their own metrics sending implementation. The OTLP Registry can still only support HTTP/protobuf as it does today but, for example, its implementation can be described by a public interface.

Rationale
The purpose of the change is to allow for metrics sending to be more flexible on the consumer side. I'm not advocating any changed to the OTLP protocols, rather my intention would be to open metrics sending up.
And example on my end would be that I desire to push all metrics to a Kafka topic before they are sent via HTTP/protobuf to OTLP collector. This way I have greater control over my metrics that might be coming from a number of microservices.

People who give this issue a 👍🏼 or 🚀, what is your use-case?

Right now, the use-case seems to be sending the data through Kafka which is not supported by the specs if I remember correctly. But I'm curious if people have other use-cases or you are co-workers and has the same use-case.

@jonatan-ivanov they are co-workers 😅
