Functional config example for doctrine with mezzio about psr-container-doctrine HOT 1 OPEN

OK, I think I managed to solve the problem.
I'll leave it registered in case someone else finds the same case as mine:

A little bit of context, as the doctrine/cache drivers are obsolete and have been removed from version 2 of the package, I had to create a new "fake" driver in order to get psr-container-doctrine to work properly, done that my code started to show the above errors, after much debugging in the doctrine's internal codes, I decided to take a look at DriverFactory's
psr-container-doctrine, and that's when I noticed the problem, it calls the AnnotationDriver inside a CachedDriver, my cache driver was without any implementation, so it didn't return anything and therefore the AnnotationDriver wasn't called.

What I did for the AnnotationDriver to be called was to recreate an implementation of the doctrine/cache ArrayDriver, for the development environment should be enough for now, then I think about another implementation with a better engine.

When I recreated the ArrayDriver implementation, my code started to recognize the entities correctly.

As mentioned in the issue below, I think it would be very useful to be able to disable the cache mechanism through the settings.
