This patch creates a new cli package that allows to combine both client and daemon commands (there is only one daemon command: docker daemon). The `-d` and `--daemon` top-level flags are deprecated and a special message is added to prompt the user to use `docker daemon`. Providing top-level daemon-specific flags for client commands result in an error message prompting the user to use `docker daemon`. This patch does not break any old but correct usages. This also makes `-d` and `--daemon` flags, as well as the `daemon` command illegal in client-only binaries. Signed-off-by: Tibor Vass <tibor@docker.com>
