Booking Future Time

Looking at the commit from the linked reference in my previous comment, I have slightly modified rfmarcelino's original code to match my needs and after some testing and to my surprise I wanted to let you know that it works and does exactly what I wanted.

I am not sure yet how to apply those commits, so please see below the attached code. Feel free to do the testing and possibly push it to the future updates. I am quite sure it can come handy.

WebformBookingController.php

    // Adjusting end date based on 'days_visible' if set.
    if (isset($config['#days_visible']) && is_numeric($config['#days_visible'])) {
      $visibleDate = (new \DateTime())->modify('+' . $config['#days_visible'] . ' days');
      if ($actualEndDate > $visibleDate) {
        $actualEndDate = $visibleDate;
      }
    }

WebformBooking.php

protected function defineDefaultProperties() {
 $properties = parent::defineDefaultProperties() + [
...
      'days_visable' => '0',
...

    // Days visable.
    $form['appointment_settings']['days_visible'] = [
      '#type' => 'number',
      '#title' => $this->t('Days Visiblee'),
      '#default_value' => $this->getDefaultProperty('days_visible'),
      '#description' => $this->t('Number of days from now a booking can be made'),
    ];

I think that at this stage we still have to create a condition that takes into account the original "Days in Advance" setting to ensure that those two not interfere with each other, i.e. "Days in Advance" number can not be higher than "Days Visible".
What do you think?

This functionality is broken for all releases starting from 1.0.13. For 1.0.13 the fix is simple but for the 1.1* versions it is not that easy to make it to work.

@rfmarcelino, can you please look into it when you have a second?

I can confirm this issue is no more in the last dev release. It can be pushed to the next stable.

@rfmarcelino, thanks!
