…ample and rescoring (elastic#125599) This allows a `rescore_vector: {oversample: 0}` to indicate bypassing oversampling and rescoring. This is useful for: - Updating a quantized mapping to turn off automatic rescoring - Bypassing oversampling at query time in an ad-hoc manner if its on by default in the mapping closes: elastic#125157 (cherry picked from commit 009a86a)
