Add filter_path to bulk message for performance improvement

[mrnonz]

Describe the solution you'd like
We should setting filter_path to as default requests to reduce the size of responses from opensearch.

During the _bulk request if errors,items.*.error,items.*.status is applied to filter_path, it should reduce > 90% of the response size from opensearch, reducing bandwidth usage and also making response processing faster (less json to deserialize).
