Zend\Session\Exception\InvalidArgumentException: Invalid save handler specified ("redis"); must be one of "files" or a class implementing SessionHandlerInterface
Expected
Either there needs to be a Redis SaveHandler class or it should be treated just like 'files'
Just upgrade from 2.8.0 to 2.8.1 and noticed that the save_handler is treated differently now
Code to reproduce the issue
You can reproduce it by using a redis server as your session handler. Here is part of our code, obviously I can't share the full thing.
Actual results
Zend\Session\Exception\InvalidArgumentException: Invalid save handler specified ("redis"); must be one of "files" or a class implementing SessionHandlerInterface
Expected
Either there needs to be a Redis SaveHandler class or it should be treated just like 'files'
Sidenote
The example in the Documentation now breaks, https://framework.zend.com/manual/2.4/en/modules/zend.session.config.html#id3
