right now, there are like 5 different places that need updating if we add a new config/cli field:
pkg/config/config.go to add it to the structure
pkg/config/template.go to add it to the man page template
internal/criocli/criocli.go to add the cli flag
docs/* and completions/* to add completions and documentation

Ideally, we could have just one (or maybe two) places we add a structure, and then we automatically generate the config structure, CLI and documentation out of that

This issue is to track that work
