Title: Added Zend_Cache adapter

I don't know whether this needed, but anyway...
I have created Cache adaptar class inherited from CacheProvider which adds ability to use Zend_Cache adapters to store Doctrine Cache.

Sample configuration could be the following:

```yaml
default:
adapterClass: Doctrine\Common\Cache\ZendCache
options:
frontendAdapter: Core
frontend:
automatic_serialization: true
backendAdapter: File
backend:
cache_dir: APPLICATION_PATH/../cache
namespace: Api
```
