[feature request] Enhancement about tweaks of yurtappset

[vie-serendipity]

What would you like to be added:
Add {{nodepool}} to replace the specified nodepool, users can batch inject configmap and secret that match the naming rules.

Why is this needed:
There may be different configmaps for different nodepools, and the user may need to write tweaks one by one. After joining {{nodepool}}, the user can bulk write by regularly naming the configmap and secret, like configmap-xxx (xxx represents the detailed name of nodepool).

@vie-serendipity It's a good idea to use {{nodepool}} to match multiple nodepools, as it allows users to easily perform batch configurations at the nodepool level.

I think we should make the definition more clearly, so how about use {{nodepool-name}} to replace {{nodepool}}?

@rambohe-ch Good idea.
