Code refactor for new service manager of ZF3

[ezimuel]

This PR contains the code refactor using the new ServiceManager of ZF3 with the following develop branches:

• "zendframework/zend-servicemanager": "dev-develop as 2.7.0"
• "zendframework/zend-stdlib": "dev-develop as 2.8.0"
• "zendframework/zend-cache": "dev-develop as 2.6.0"
• "zendframework/zend-config": "dev-develop as 2.6.0"
• "zendframework/zend-mvc": "dev-develop as 2.7.0"
• "zendframework/zend-view": "dev-develop as 2.6.0"

I removed Zend\Paginator\Adapter\Callback because Zend\Stdlib\CallbackHandler doesn't exist anymore in develop branch of zend-stdlib.

@ezimuel I think we could alter the callback paginator to use PHP callables instead. Do you want me to do this via an additional PR, or do you want to handle it?

@weierophinney please do it, thanks!
