As mentioned on OpenSearch issue 4780, some transport layer SSL options have changed. The old options are now deprecated.

I am unsure the full list of options that are deprecated. Is it all plugins.security.ssl.transport.* turns to transport.ssl.* ? If so, please let me know and I can prepare a pull request.

The current changes I'm aware of are:

• plugins.security.ssl.transport.enforce_hostname_verification => transport.ssl.enforce_hostname_verification
• plugins.security.ssl.transport.resolve_hostname => transport.ssl.resolve_hostname

Version:
2.19.1

I've submitted a PR for those two options (#9602). Do you know if there are any other options that were deprecated @Naarcha-AWS ?

It looks to me like these changes came out of #12435. Based on that, it looks to me like it's just these two, but I'm not experienced enough with Java to really know for sure.
