interface MediaSourceFieldConstraintsInterface in Drupal 8

Defines an interface for a media source with source field constraints.

This allows a media source to optionally add source field validation constraints for media items. To add constraints at the entity level, a media source can also implement MediaSourceEntityConstraintsInterface.
