Events Logging

NOT YET READY FOR PRODUCTION USAGE
This module implements an out-of-the-box events logging system with standard content entities.
It also provides a standard drupal view of events, so you can track the operation on all content entities and configuration entities.
It’s also possible to log custom events using the logger standard service provided by this module.
Storage backends for logs are defined as plugins so you can easily extend this module to create your own logging plugin.
