ZF-10220: Zend_Cache_Manager has no way to get all the caches
Sometime is usefull to get the list of all the caches handled by cache manager.
However, even if the cache manager has a protected
protected $_caches = array();
it doesn't offer any way to return back all the caches (or caches names).
This could be useful in certain situations, i would only mention the need to cleanup all the caches...
