Feel free to create JIRA for put username in logout event details.

The possibility to retrieve username in logout events is alreadt doable 
though, but it's a bit complicated. You will need to pass 
KeycloakSession to your EventListener implementation (KeycloakSession is 
available in EventListenerProviderFactory.create() ). Then once you have 
KeycloakSession you can use it to lookup realm and then username based 
on userId. Something like this:
RealmModel realm = session.getContext().getRealm();
UserModel user = session.users().getUserById(userId, realm);
String username = user.getUsername();
