Vincent Demeester 69fdd2a4ad formatter package heavy refactoring
- 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.
