Sebastiaan van Stijn 5ee2906e78 cli/flags: use a regular StringArray for the --host / -H flag
The ClientOptions struct and related flags were inherited from the Moby
repository, where originally the CLI and Daemon used the same implementation
and had a "Common" options struct. When the CLI moved to a separate repository,
those structs were duplicated, but some daemon-specific logic remained. For
example, the daemon can be configured to listen on multiple ports and sockets
([moby@dede158]), but the CLI [can only connect to a single host][1]. The
daemon config also had to account for flags conflicting with `daemon.json`,
and use special flag-vars for this ([moby@677a6b3]).

Unfortunately, the `ClientConfig` struct became part of the public API and
is used as argument in various places, but we can remove the use of the
special flag var. This patch replaces the use of `NewNamedListOptsRef`
for a regular `StringArray`.

Unfortunately this changes the flag's type description from `list` to
`stringArray`, but we can look at changing that separately.

The non-reference docs have been moved!

The documentation for Docker Engine has been merged into the general documentation repo.

See the README for instructions on contributing to and building the documentation.

If you'd like to edit the current published version of the Engine docs, do it in the master branch here: https://github.com/docker/docker.github.io/tree/master/engine

If you need to document the functionality of an upcoming Engine release, use the vnext-engine branch: https://github.com/docker/docker.github.io/tree/vnext-engine/engine

The reference docs have been left in docker/docker (this repo), which remains the place to edit them.

The docs in the general repo are open-source and we appreciate your feedback and pull requests!
