Content translation/Product Definition/Translation view

Publish action
On normal circumstances, the publish action should publish the content and lead you to the saved page. Once there it would be good to provide a bit of context and additional instructions to encourage improving the article (regarding the second part, we can create a new story for the future).

On special circumstances, a callout menu is shown to inform of such circumstances, and ask the user to confirm to proceed.

Special circumstances include (more to be added):
 * The article already exists.
 * The translation has too much of automatic translation.
