opensearch: generalize extra parameters

[DonHaul]

The current OpenSearch hook, does not include the possibility to set arguments for the opensearch client that may be important for some users such as http_compress and url_prefix etc. opensearchpy library supports many more arguments, including kwargs - see here
As such I've generalized the hook so all the parameters in extra are passed to the opensearch client

I think it is too generic as it might update things we do not want to update via extras. Extras are potentially more sensitive than Hook parameters, because they are configurable by "connection editing" users and not "Dag Authors" - we never pass extras directly to hoo params/args we are always explicit which extras should be passed.

okay I will specifically define all the parameters in https://opensearch-project.github.io/opensearch-py/_modules/opensearchpy/connection/base.html#Connection . I see that the kwargs is actually only scheme so I will add it as an arg as well
