How about also adding a test to validate if pd-ctl can work normally?

How about also adding a test to validate if pd-ctl can work normally?

I would like to add it in #7076 after merging this PR to test the scheduler with pd-ctl as well.

No, the meta info should all be managed in the API server, and the scheduling service will watch them.
