Metadata and Memcached

[rawkode]

It also appears that clearing the metadata cache doesn't work with memcached

To reproduce:

Create an entity and store cache in memcached
Edit / Add / Remove a column from the entity and attempt to perform a doctrine schema update

There is a --flush option to the app/console doctrine:cache:clear-metadata command which will flush Memcached, Redis, etc. This is a bit dangerous if your doctrine cache is not in an isolated namespace or Redis database though.
