ZF-2469: missing method Zend_Cache_Core::getBackend

Description

The frontend cache object store the backend object but the backend object can't get from outside of the cache frontend to change backend options or other things

e.g.


$cache = Zend_Cache::factory('Core', 'File');
$backend = $cache->getBackend();  // <- This method is missing
$backend->setCacheDir('./my/new/Cache/Directory');
