Provides a listing of robot entities.
List Controllers provide a list of entities in a tabular form. The base class provides most of the rendering logic for us. The key functions we need to override are buildHeader() and buildRow(). These control what columns are displayed in the table, and how each row is displayed respectively.
Drupal locates the list controller by looking for the "list" entry under "controllers" in our entity type's annotation. We define the path on which the list may be accessed in our module's *.routing.yml file. The key entry to look for is "_entity_list". In *.routing.yml, "_entity_list" specifies an entity type ID. When a user navigates to the URL for that router item, Drupal loads the annotation for that entity type. It looks for the "list" entry under "controllers" for the class to load.
