fc7b904dce Add new HostConfig field, Mounts.
`Mounts` allows users to specify in a much safer way the volumes they
want to use in the container.
This replaces `Binds` and `Volumes`, which both still exist, but
`Mounts` and `Binds`/`Volumes` are exclussive.
The CLI will continue to use `Binds` and `Volumes` due to concerns with
parsing the volume specs on the client side and cross-platform support
(for now).

The new API follows exactly the services mount API.

Example usage of `Mounts`:

```
$ curl -XPOST localhost:2375/containers/create -d '{
  "Image": "alpine:latest",
  "HostConfig": {
    "Mounts": [{
      "Type": "Volume",
      "Target": "/foo"
      },{
      "Type": "bind",
      "Source": "/var/run/docker.sock",
      "Target": "/var/run/docker.sock",
      },{
      "Type": "volume",
      "Name": "important_data",
      "Target": "/var/data",
      "ReadOnly": true,
      "VolumeOptions": {
	"DriverConfig": {
	  Name: "awesomeStorage",
	  Options: {"size": "10m"},
	  Labels: {"some":"label"}
	}
      }]
    }
}'
```

There are currently 2 types of mounts:

  - **bind**: Paths on the host that get mounted into the
    container. Paths must exist prior to creating the container.
  - **volume**: Volumes that persist after the
    container is removed.

Not all fields are available in each type, and validation is done to
ensure these fields aren't mixed up between types.

b0ac69b67e Add explicit flags for volume cp/no-cp
This allows a user to specify explicitly to enable
automatic copying of data from the container path to the volume path.
This does not change the default behavior of automatically copying, but
does allow a user to disable it at runtime.
