SSH commands for kic

[medyagh]

for a better unifying experience, we need to handle ssh commands for kic as well

// RunSSHCommandFromDriver implements direct ssh control to the driver
func (d *Driver) RunSSHCommandFromDriver() error {
	return fmt.Errorf("driver does not support RunSSHCommandFromDriver commands")
}

I suspect we might need to implement a NewBuildrootProvisioner

func NewBuildrootProvisioner(d drivers.Driver) provision.Provisioner {
	return &BuildrootProvisioner{
		provision.NewSystemdProvisioner("buildroot", d),
	}

the current one uses https://github.com/machine-drivers/machine

alternatively we could make a factory that Turns a kic runner to machine-driver's ssh.Cllient
but that would loos all the nice interface we have for command runner to set stdin and stdout and we need to convert to this interface:

type Client interface {
	Output(command string) (string, error)
	Shell(args ...string) error

	// Start starts the specified command without waiting for it to finish. You
	// have to call the Wait function for that.
	//
	// The first two io.ReadCloser are the standard output and the standard
	// error of the executing command respectively. The returned error follows
	// the same logic as in the exec.Cmd.Start function.
	Start(command string) (io.ReadCloser, io.ReadCloser, error)

	// Wait waits for the command started by the Start function to exit. The
	// returned error follows the same logic as in the exec.Cmd.Wait function.
	Wait() error
}
