Hide legacy top-level "deploy" command with DOCKER_HIDE_LEGACY_COMMANDS=1 

The `DOCKER_HIDE_LEGACY_COMMANDS` environment variable allows hiding legacy
top-level commands that are now available under `docker <object> <verb>`. The
`docker deploy` top-level command is experimental, and replaced by
`docker stack deploy`.

This patch hides the top-level `docker deploy` if the `DOCKER_HIDE_LEGACY_COMMANDS`
environment variable is set.

Before this change:

    DOCKER_HIDE_LEGACY_COMMANDS=1 docker --help

    ...

    Commands:
      build       Build an image from a Dockerfile
      deploy      Deploy a new stack or update an existing stack
      login       Log in to a Docker registry
      logout      Log out from a Docker registry
      run         Run a command in a new container
      search      Search the Docker Hub for images
      version     Show the Docker version information
    ...

With this patch applied:

    DOCKER_HIDE_LEGACY_COMMANDS=1 docker --help

    ...

    Commands:
      build       Build an image from a Dockerfile
      login       Log in to a Docker registry
      logout      Log out from a Docker registry
      run         Run a command in a new container
      search      Search the Docker Hub for images
      version     Show the Docker version information
    ...
