Enables custom meta model names (thus also ember model names) to allow flow model with the same name from different namespaces.

Model names can now be configured through Ember\Resource and Ember\Model annotations. Example:
/** @Ember\Resource(modelName="coffee") */
OR
/** @Ember\Model(name="coffee") */

Model names can also be configured through Ember.yaml. Example:
Mmitasch:
  Taskplaner:
    models:
      'Acme\Demo\Domain\Model\CoffeeBean':
        name: 'coffee'

Ember.yaml config has precedence over annotation as usual.

In case of duplicate model names a runtime exeption is thrown.
