Follow-up to #2350503: Add route generation handlers for entities
Problem/Motivation
We now have support for route auto-generation for entities. Let's use it for all entities.
Proposed resolution
Implement any additional route generators we need, and remove all static routes in yml files.
Remaining tasks
Do it.
Also make sure the Entity topic is updated as part of this patch. (@defgroup entity_api in entity.api.php).
User interface changes
None.
API changes
None.
