Add support for security plugin

[10000-ki]

Is your feature request related to a problem?

https://github.com/elastic/elasticsearch-java/tree/main/java-client/src/main/java/co/elastic/clients/elasticsearch/security

As you may know, elasticsearch-java-client supports SecurityClient
This is a class that provides security-related convenience features.

Are there any plans to bring the Security Client to the OpenSearch Java Client?

Yes, we'd like support for the security plugin the client. The grand plan is to generate most of that code from spec (see #366), a lot of the spec for the security plugin has already been contributed to https://github.com/opensearch-project/opensearch-api-specification. We could definitely use some help!

@dblock Thanks for explaining

#366

This work seems to have stalled over the past year.
I was wondering if there are any plans to continue development or if you would like someone to contribute.

@Xtansia is actively working on the generator, however we would love help on the various specs
