interface WorkspaceAssociationInterface in Drupal 8

Defines an interface for the workspace_association service.

The canonical workspace association data is stored in a revision metadata field on each entity revision that is tracked by a workspace.

For the purpose of optimizing workspace-specific queries, the default implementation of this interface defines a custom 'workspace_association' index table which stores only the latest revisions tracked by a workspace.
