[BUG]org.opensearch.integtest.config.ChimeNotificationConfigCrudIT failed when running integration tests with OpenSearch rpm/deb package

[gaobinlong]

What is the bug?

There's an integration test failure when running tests with OpenSearch rpm/deb package, it seems that we do not handle the warnings correctly when calling _refresh API:

Warnings: [this request accesses system indices: [.opendistro_security], but in a future major version, direct access to system indices will be prevented by default, this request accesses system indices: [.opensearch-notifications-config], but in a future major version, direct access to system indices will be prevented by default]

, we need to dive deep on this and fix it.

What is the expected behavior?
Integration tests runs successfully with rpm/deb package.

Do you have any screenshots?
