Expose package as a config-provider / ZF component

Added:

- `ConfigProvider`, which enables the
  `StorageCacheAbstractServiceFactory` by default, as well as maps new
  entries for the `PatternPluginManager`, storage `PluginManager`, and
  storage `AdapterPluginManager`.
- `Module`, which does the same as the above, but in a zend-mvc context.
