[META] Multi-tenancy support in OpenSearch

[ansjcy]

Please describe the end goal of this project

Introduce and enable multi-tenancy as a first class citizen in OpenSearch by associating traffic with specific users or workloads. This will allow better categorization, management, troubleshooting and analysis of subsets of traffic hitting an OpenSearch cluster.

We can start from the search use cases and build a generic framework/solution, which can be extend it to other workflow like indexing.
