CustomField label loading in storefront

We want to provide the labels of custom fields in the storefront to third party developers. On one hand we could add the labels to every loaded entity, but this will cause a heavy leak of performance and the labels are often not used in the template.


We implemented a subscriber, which listen on the custom_field.written event to add also snippets to all snippet sets with the given label translations of the custom field. The translationKey of the snippets are prefixed with customFields., followed by the technical name of the custom field. Thus the snippets can be used in the storefront.


Inserting a custom field always creates new snippet with the given label translations.
