Add support for "rescore" query in SSR.

**Affected Projects**
React

**Is your feature request related to a problem? Please describe.**
Elasticsearch supports `rescore` query, that allows us to re-rank results based on some function. Machine Learning models use this rescore query to re-rank results based on the business logic. It works on client side but not with SSR.

For reference - https://www.elastic.co/guide/en/elasticsearch/reference/6.8/search-request-rescore.html

**Describe the solution you'd like**
A possible solution would be adding support for the `rescore` query in the `defaultQuery` function of `ReactiveList` component.
