Feat: print addon parameters recursively

[charlie0129]

Description of your changes

Previously, we can only view the top-level parameters.
Notice the nested objects didn't show up.

Now we can show nested parameters no matter how deep they are.
Also with their default/current values.

I have:

• Read and followed KubeVela's contribution process.
• Related Docs updated properly. In a new feature or configuration option, an update to the documentation is necessary.
• Run make reviewable to ensure this PR is ready for review.
• Added backport release-x.y labels to auto-backport this PR if necessary.

How has this code been tested
