 // ContainerAttach attaches a connection to a container in the server.
 // It returns a types.HijackedConnection with the hijacked connection
 // and the a reader to get output. It's up to the called to close
 // the hijacked connection by calling types.HijackedResponse.Close.

 //
 // The stream format on the response will be in one of two formats:
 //
 // If the container is using a TTY, there is only a single stream (stdout), and
 // data is copied directly from the container output stream, no extra
 // multiplexing or headers.
 //
 // If the container is *not* using a TTY, streams for stdout and stderr are
 // multiplexed.
 // The format of the multiplexed stream is as follows:
 //
 //    [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4}[]byte{OUTPUT}
 //
 // STREAM_TYPE can be 1 for stdout and 2 for stderr
 //
 // SIZE1, SIZE2, SIZE3, and SIZE4 are four bytes of uint32 encoded as big endian.
 // This is the size of OUTPUT.
 //
 // You can use github.com/docker/docker/pkg/stdcopy.StdCopy to demultiplex this
 // stream.
