Description
Currently the encoder only supports a single metric. There is no concept like metrics lists.
It's not uncommon that collectors get raw data from their source and generate a list of metrics from that.
Right now it seems like we have to register every metric, but it would be great if we had a way to generate metrics on the fly on every scrape and pass them to the encoder.
Or am I just missing the right module?

Research direction
Start by tracing the encoder and the metric registration path mentioned in the issue, then inspect how collectors currently produce metrics during a scrape. Define the supported list-generation flow and verify that dynamically generated metrics can be encoded without individual registration.
