- make it possible to extract the formatter implementation from the "common" code, that way, the formatter package stays small - extract some formatter into their own packages This is essentially moving the "formatter" implementation of each type in their respective packages. The *main* reason to do that, is to be able to depend on `cli/command/formatter` without depending of the implementation detail of the formatter. As of now, depending on `cli/command/formatter` means we depend on `docker/docker/api/types`, `docker/licensing`, … — that should not be the case. `formatter` should hold the common code (or helpers) to easily create formatter, not all formatter implementations.
