### What would you like to be added ?

pipeline build the phy plan NEEDs consider CNs' real #cpu and #mem resources. NOT ALL CN have same #cpu resource.
```

### Why is this needed ?

Base on scale up/down NEEDs from Cloud, https://github.com/matrixorigin/matrixone/issues/16537 passing cn's real #cpu and #mem to the clusterservice / hakeeper.

`getCNList()` returns CN List with real resources setting.
