What's changed and what's your intention?

See https://github.com/risingwavelabs/risingwave/pull/15611 for changes on kernel side. In short, #15611 will deprecate the existing standalone mode and use single-mode for both community user's deployment and cloud deployment.

This PR must NOT merge before #15611 get merged.

Is this still needed?

I don't know. I assume it isn't.

Is this still needed?

Hmmm, I think yes. We plan to deprecate risingwave standalone in the long term, this is one of the steps.
