This fix tries to address the comment https://github.com/docker/docker/pull/30376#discussion_r97465334
where it was not possible to specify `--format` for `docker node ls`. The `--format` flag
is a quite useful flag that could be used in many places such as completion.
This fix implements `--format` for `docker node ls` and add `nodesFormat` in config.json
so that it is possible to specify the output when `docker node ls` is invoked.
Related documentations have been updated.
A set of unit tests have been added.
This fix is related to #30376.

Start work on adding unit tests to our cli code in order to have to
write less costly integration test.

In file `api/types/client.go`, some of the "*Options{}" structs own a
`Filters` field while some else have the name of `Filter`, this commit
will rename all `Filter` to `Filters` for consistency. Also `Filters`
is consistent with API with format `/xxx?filters=xxx`, that's why
`Filters` is the right name.
