Both 'consul config write' and server bootstrap config entries take a decoding detour through mapstructure on the way from HCL to an actual struct. They both may take in snake_case or CamelCase (for consistency) so need very similar handling. Unfortunately since they are operating on mirror universes of structs (api.* vs structs.*) the code cannot be identitical, so try to share the kind-configuration and duplicate the rest for now.
