Description

When using a PSR11 Container such as elie29/zend-di-config it is not possible to use the included delegator factory as it is hardcoded to use the Interop\Container\ContainerInterface, even though that interface has extended Psr\Container\ContainerInterface for some time now.

This PR swaps out for the Psr version thus allowing PSR11 containers to be configured.

Fixes #24

Note to myself: since the class was final and container-interop implements the psr interface, we do still accept interop interfaces and thus this should not be a BC break.
Have to double check this when I have some more time, but afaik we do conflict in laminas-cache with container-interop <1.2

Sorry that it takes that long @cooperaj

[cooperaj]

No worries. I'll be honest, I was confused about the BC break but I wasn't going to argue with the maintainer ;)

To summarize

This is no BC break due to the fact, that laminas/laminas-cache since v3 requires laminas/laminas-servicemanager in v3.7.0+.
laminas/laminas-servicemanager in v3.7.0+ requires container-interop/container-interop v1.2.0+.
container-interop/container-interop in v1.2.0+ implements psr/container and thus, we do still accept the injection of container-interop container instances.

Thanks, @cooperaj!
