Support for custom switch

Not sure if I'm missing something, but I don't see support for custom-switch control without passing new templates in the control() function. I was wondering if you could add 'switch' to $options and make minor code adjustments.

I've added the following templates:

'customSwitchContainer' => '<div class="form-group custom-control custom-switch {{type}}{{required}}">{{content}}{{help}}</div>',
'customSwitchContainerError' => '<div class="form-group custom-control custom-switch {{type}}{{required}} is-invalid">{{content}}{{error}}{{help}}</div>',
'customSwitchInlineContainer' => '<div class="form-group custom-control custom-switch custom-control-inline {{type}}{{required}}">{{content}}</div>',
'customSwitchInlineContainerError' => '<div class="form-group custom-control custom-switch custom-control-inline {{type}}{{required}} is-invalid">{{content}}</div>',
'customSwitchWrapper' => '<div class="custom-control custom-switch">{{label}}</div>',
'customSwitchInlineWrapper' => '<div class="custom-control custom-switch custom-control-inline">{{label}}</div>',

'customSwitchFormGroup' => '<div class="%s"><div class="custom-control custom-switch">{{input}}{{label}}</div>{{error}}{{help}}</div>',

Code adjustment in the control() function:

if (empty($options['switch'])) {
  if ($this->_align === 'horizontal') {
      $options['templates']['checkboxFormGroup'] = $this->templater()->get('customCheckboxFormGroup');
  } else {
      $options['templates']['checkboxContainer'] = $this->templater()->get('customCheckboxContainer');
      $options['templates']['checkboxContainerError'] = $this->templater()->get('customCheckboxContainerError');
  }
} else {
  if ($this->_align === 'horizontal') {
      $options['templates']['checkboxFormGroup'] = $this->templater()->get('customSwitchFormGroup');                          
  } else {
      $options['templates']['checkboxContainer'] = $this->templater()->get('customSwitchContainer');
      $options['templates']['checkboxContainerError'] = $this->templater()->get('customSwitchContainerError');
  }
}

and:

if ($inline ||
    $this->_align === 'inline'
) {
    if (!$custom) {
        $options['templates']['checkboxContainer'] = $this->templater()->get('checkboxInlineContainer');
        $options['templates']['checkboxContainerError'] = $this->templater()->get('checkboxInlineContainerError');
    } else {
        if (empty($options['switch'])) {
          $options['templates']['checkboxContainer'] = $this->templater()->get('customCheckboxInlineContainer');
          $options['templates']['checkboxContainerError'] = $this->templater()->get('customCheckboxInlineContainerError');
        } else {
          $options['templates']['checkboxContainer'] = $this->templater()->get('customSwitchInlineContainer');
          $options['templates']['checkboxContainerError'] = $this->templater()->get('customSwitchInlineContainerError');
        }
    }
}

So my calling code is simply:

$this->Form->control('is_active', ['custom' => true, 'switch' => true]);

I've no need for multiswitch controls, but I believe code to add would be straightforward.
