Description
In order to remove Application reliance on service locator pattern default listeners need to be extracted from Application class. Newly introduced ApplicationListenersProvider takes responsibility of registering default listeners.
Its factory is looking for a config key
$config[Application::class]['listeners']
for additional listeners, removing the responsibility from application factory.ApplicationListenersProvider is not a PSR listener provider.
It operates exclusively on laminas-eventmanager listener aggregates and does not actually allow listeners to be directly registered.
Another approach I considered was to use config provider and configuration to define default listeners. This double-dispatch approach however is more sound in ensuring listeners are always attached on Application instantiation.
Psalm issues which are not directly related intentionally left unfixed to be handled in a separate PR.
Documentation for the changes is to be done via separate PR. See #58
