Unified OpenSearch CLI RFC

I thought I would signal boost this RFC that was published in the CLI repo to unify the 3 CLIs (SQL, OpenSearch, and perftop) so that there is a single installable to do any of the tasks. VijayanB and I are both curious about popular package managers people use and if there is a preference on versioning being coupled with OpenSearch or decoupled. Please share thoughts in the GitHub issue.
