When use `docker stats` to minitor a running container and then stop it,
there are some fields need to be reset to zero. Otherwise it will keep
displaying the data it received last time.

For now docker stats will sum the rxbytes, txbytes, etc. of all
the interfaces.
It is OK for the output of CLI `docker stats` but not good for
the API response, especially when the container is in sereval
subnets.
It's better to leave these origianl data to user.

For now CLI `docker stats` will not block even if the container was
not running is because there is a 2s timeout setting when waiting for
the response.
I think why we hang there waiting for the container to run is because we
want to get the stats of container immediately when it starts running.
But it will block when use the API directly, for example
- curl
- Google Chrome plugin, Postman
- Firefox plugin, RESTClient
This patch keeps the feature that getting info immediately when container
starts running and in the meantime, it will not block when using the API
directrly.

* Add space between values in docker stats output for easier parsing
Old output could not be parsed easily because there were columns
that did not have any separator. Also values that are together
without any space is difficult to read even for humans.
* Update unit.HumanSize comment to match what the does actually does

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.

Adds a `stream` query param to the stats API which allows API users to
only collect one stats entry and disconnect instead of keeping the
connection alive to stream more stats.
Also adds a `--no-stream` flag to `docker stats` which does the same
