Two possible solutions:

• Remove format_verison and format_uuid. This may lead to breaking change when config schemas are changed in the future.
• Add auto migration.
  Which do you prefer? @harry-xi

When I write this issues, I think it can be resolved by an auto migration tool.

But I think remove theme are still a good way: for a file with most of keys are optional and it is less likely to change the meaning of them. I think break change are almost impossible.

nice, could you help me impl this? via PR plz.

So which way do we choose? auto migration or remove format_verison and format_uuid.

we could simply remove the required format version and uuid keys
