Add icon to Openstack Cloud Service Provider Form

@jigishaddweb

Thank you for adding the icon. It looks working but while saving an OpenStack cloud service provider, I received the following error:

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "entity:cloud_config:openstack" plugin does not exist.

Could you please take a look at it?
