Title: [Persistence] Add clear() to ObjectManager interface

I'm not sure why this method was omitted from the interface, since `detach()` is present and both ORM/ODM implement a `clear()` method (despite ODM currently not supporting the `$objectName` filter).

If this is worth merging, someone might also want to consider adding `close()` to the interface.
