Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

`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.

Docker creates a UTS namespace by default, even with --net=host, so it
is reasonable to let the user set the hostname. Note that --hostname is
forbidden if the user specifies --uts=host.

The parse.go file is used almost exclusively in the client. The few small
functions that are used outside of the client could easily be copied out
when the client is extracted, allowing this runconfig/opts package to
move to the client.
