Button group which would allow setDisableOnClick for more than one button

ButtonGroup for V14

Very simple implementation of group of Buttons. The main use-case is for allowing setDisableOnClick for a group of Buttons.

The implementation is based on com.vaadin.flow.component.button.Button's disableOnClick implementation.

Usage example

Button button1 = new Button("Button 1");
Button button2 = new Button("Button 2");
Button button3 = new Button("Button 3");
buttons = Arrays.asList(button1, button2, button3);

// add buttons to ButtonGroup before adding click listeners
ButtonGroup buttonGroup = new ButtonGroup(buttons);
// enable disableOnClick
buttonGroup.setDisableOnClick(true);

// add button specific click listeners
buttons.forEach(b -> b.addClickListener(e -> {
    try {Thread.sleep(5000L);} catch (InterruptedException ex) {}
    buttonGroup.setEnabled(true);
}));

// add button group to a layout
add(buttonGroup);
