fix: avoid parsing search malformed requests

[etolbakov]

Description

ES compatible API does not accept malformed requests and returns 400 and the following body instead

{
    "message": "unknown field `term`, expected one of `from`, `size`, `query`, `sort`, `aggs`, `track_total_hits`, `stored_fields`, `search_after` at line 1 column 7"
}

How was this PR tested?

a unit test has been added, local testing with the change has been done as well

Can we have a look at other nested structure?

I'm sure some of the query alternative in the query dsl are missing the deny_unknown_fields annotation

    QueryString(QueryStringQuery),
    Bool(BoolQuery),
    Term(TermQuery),
    Terms(TermsQuery),
    MatchAll(MatchAllQuery),
    MatchNone(MatchNoneQuery),
    Match(MatchQuery),
    MatchBoolPrefix(MatchBoolPrefixQuery),
    MatchPhrase(MatchPhraseQuery),
    MatchPhrasePrefix(MatchPhrasePrefixQuery),
    MultiMatch(MultiMatchQuery),
    Range(RangeQuery),
    Exists(ExistsQuery),

@fulmicoton
I had a look at it and the good news is that almost all of the ElasticQueryDslInner members have deny_unknown_fields.
I've added it where I find reasonable. Could you please take a look?
As for TermQuery, MatchNoneQuery, MultiMatchQuery not sure if it's needed.
