feat(query): Make BooleanQuery supports minimum_number_should_match (#2405)

Browse Source 
* feat(query): Make `BooleanQuery` supports `minimum_number_should_match`. see issue #2398

In this commit, a novel scorer named DisjunctionScorer is introduced, which performs the union of inverted chains with the minimal required elements. BTW, it's implemented via a min-heap. Necessary modifications on `BooleanQuery` and `BooleanWeight` are performed as well.

* fixup! fix test

* fixup!: refactor code.

1. More meaningful names.
2. Add Cache for `Disjunction`'s scorers, and fix bug.
3. Optimize `BooleanWeight::complex_scorer`

Thanks
 Paul Masurel <paul@quickwit.io>

* squash!: come up with better variable naming.

* squash!: fix naming issues.

* squash!: fix typo.

* squash!: Remove CombinationMethod::FullIntersection
