The prompb and prompbmarshal share exactly the same models and provide
marshal and unmarshale capabilities for them. This creates duplication
(changes in one model has to be made in another, case with metadata) and
confusion where for example you compare same looking models but golang
says they are not the same (because of the type).
This commit merge prompbmarshal logic into prompb so the rest of the
code is aligned on prompb models.
Moves samplesPool and labelsPool to WriteRequestUnmarshaller.
Make WriteRequest struct clean from unmarshal logic.
The benchmark shows no significant changes:
