How to invoke plugin using opensearch-java client library?

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): OpenSearch 2.8.0
Describe the issue: We have custom opensearch plugin. We have been using rest high level client. Since rest high level client will be deprecated from OpenSearch 3.0.0 onwards, we want to migrate to opensearch-java client library. How do we invoke customer plugin from opensearch-client APIs. In order to use opensearch-java client library, I had to make changes in org.opensearch.client.opensearch._types.aggregations.Aggregate, org.opensearch.client.opensearch._types.aggregations and some other files. Please share if there any way I can use our plugin without making changes to client library.

[FEATURE] Support for composing query variants from 3rd party plugins

enhancement

### Is your feature request related to a problem? Some plugins such as the [O…penSearch LTR plugin](https://github.com/opensearch-project/opensearch-learning-to-rank-base) add additional query variants https://elasticsearch-learning-to-rank.readthedocs.io/en/latest/searching-with-your-model.html#searching-with-ltr. opensearch-java current cannot support construction of a query containing such a query variant as [QueryVariant](https://github.com/opensearch-project/opensearch-java/blob/main/java-client/src/main/java/org/opensearch/client/opensearch/_types/query_dsl/QueryVariant.java#L44) interface requiring a kind being specified and [Query.Kind](https://github.com/opensearch-project/opensearch-java/blob/main/java-client/src/main/java/org/opensearch/client/opensearch/_types/query_dsl/Query.java#L69) being a enum, not allowing for variants to be specified in a 3rd party client. ### What solution would you like? There would be a couple possible solutions to this problem. Converting the enum to a type which allows for open extension might be one. Add a `custom` variant to the enum which itself allows for a flexible query construction might be another. ### What alternatives have you considered? See above ### Do you have any additional context? N/A
