Remove zend-hydrator dependency

As of zend-hydrator 2.2.0, the component now exposes its own hydrator plugin
manager factory and wires it with the zend-modulemanager `ServiceListener`; it no
longer is a requirement of zend-mvc.

+## Hydrator integration
+
+In version 2, zend-mvc exposed a `HydratorManager` service by default, and
+provided specifications to zend-modulemanager's `ServiceListener`
+to allow modules to provide hydrator configuration.
+
+This functionality is now removed from zend-mvc. It is now exposed directly by
+the [zend-hydrator](https://zendframework.github.io/zend-hydrator/) component
+itself. To add it, install zend-hydrator:
+
+```bash
+$ composer require zendframework/zend-hydrator
+```
