DocumentStore - Reusing the same opensearch client

[quasi-deus]

Hello. So this is in regards to haystack-core-integrations; the opensearch/documentstore module. I am essentially trying to use the same Opensearch client to use for different OpensearchDocumentStore objects. I understand that allowing modification of the index for a given document store would be antipattern with the DocumentStore component, but
I want to know if it is possible to allow manually setting opensearch client; especially if it is associated with a cloud service. This way I can use the same opensearch http client and have a factory for different documentstore indicies. I don't mind contributing a PR for it, since its simple enough, but from a design perspective, is this considered acceptable?
