[FEATURE] Functionality to create aggregation queries when moving from olivere to opensearch-go

[Krithika9395]

Is your feature request related to a problem?

We are currently using https://github.com/olivere/elastic in our go service but since it's been deprecated, we have started switching to used opensearch-go. There was functionality related to creating aggregation queries in olivere, that is not available in opensearch-go.

What solution would you like?

Is there any plan to implement this in the future?

What alternatives have you considered?

Currently using the existing library to form the aggregation queries.

Do you have any additional context?

@Krithika9395 Assuming this is something supported by OpenSearch then we would like to support it. Want to try and help?
