Catlet reverse config: effective config output

[fw2568]

Currently, the output of a reverse-generated catlet config only shows the direct config of the catlet. It is therefore necessary to look up the parent config and merge it manually to get the effective config with all config from the parent and fodder.

Instead there should be options to configure the output:

• expand [just a proposal] - will generate the config with all effective config
• unresolved - without resolving parent and genes for use cases where it should always fetch latest version.
