Use youtube-nocookie.com for video embedding

[jandd]

Is your feature request related to a problem? Please describe.
The current video plugin embeds videos from the main youtube.com domain which is setting several cookies. Youtube provides a second domain youtube-nocookie.com that does not set cookies. Using that second domain would improve our user's privacy.

Describe the solution you'd like
The djangocms_video plugin should support the nocookie domain.

Additional context
I created a PR to implement this feature at django-cms/djangocms-video#56

Are we really using this plugin? At least our user facing page uses a "normal" template with a hardcoded youtube url.

See: https://github.com/devdaydresden/devday_website/blob/development/devday/talk/templates/talk/talk_details.html#L46

Am I missing something? Shall I fix this part of the code to use the nocookie-domain?

The code in the talk pages could be fixed indeed. The plugin is used in CMS pages i.e. our front page currently.
