Option to replace the system "Save" button with the "Save and Clear Cloudflare Cache" button

Hi @hktang,
Great meeting you at DrupalCon Nara!
This is great, I think best would be to have the checkbox to activate/deactivate this functionnality and when checked:

• "Save" button is renamed "Save without purging cloudflare cache", and becomes a secondary button
• "Save and purge cloudflare cache" is renamed "Save" and becomes the primary button

So the two options are offered to the user, but the default becomes the renamed purge button. This avoid confusion to most users and enable the new feature by default. This would be my suggestion.

Thanks!

I think this could work really well alongside #3479228: Add disable option and confirm option as safeguards, so that you could use Config Split or settings.php hardcoding to control which environments have Cloudflare enabled using #3479228, then use this change to make the "save" button always clear the caches on environments where CF is enabled.

Contrary to #8, could this actually go a step further and just add an extra submit handler on $form['actions']['submit'], rather than as part of $form['actions']['cf_purge'], if the option is enabled? That way it would end up something like this:

      if ($user && $user->hasPermission('cloudflare_node_cc purge cache per node')) {
        $config = \Drupal::config('cloudflare_node_cc.settings');

        // Just add the Cloudflare purge operation to the normal save operation.
        if ($config->get('replace_default_save_button')) {
          $form['actions']['submit']['#submit'][] = '_cloudflare_node_cc_purge_node';
        }

        // Add a new button to purge CF.
        else {
          $cf_purge_button = !empty($form['actions']['submit']) ? $form['actions']['submit'] : [];
          $cf_purge_button['#value'] = $t('Save & Purge Cloudflare Cache');
          $cf_purge_button['#button_type'] = 'secondary';
          $cf_purge_button['#submit'][] = '_cloudflare_node_cc_purge_node';
          $cf_purge_button['#weight']++;
          $form['actions']['cf_purge'] = $cf_purge_button;
        }
      }

Also, #3507723: Use configuration for storing configuration might be useful too.

A version of MR 10 that works on top of #3507723: Use configuration for storing configuration.

Committed. Thank you.
