Title: Make Doctrine caching class more configurable.

Now caching class can be:

* ApcCache
* ArrayCache
* Cache
* CacheProvider
* MemcacheCache
* MemcachedCache
* WinCacheCache
* XcacheCache
* ZendDataCache

to configure set:

```php
array(
'doctrine.odm.mongodb.metadata_cache' => 'ApcCache',
),
```

with appropriate caching system do you require.
