This change forbids negative field boost in the `query_string`, `simple_query_string` and `multi_match` queries. Negative boosts are not allowed in Lucene 8 (scores must be positive). The backport of this change to 6x will turn the error into a deprecation warning in order to raise the awareness of this breaking change in 7.0. Closes elastic#33309
