Makes list method not abstract
Any implementations of key_manager that don't have "list"
defined (i.e. ConfKeyManager in Nova and Cinder) will not be
instantiable if they try to use a version of Castellan
that was released after "list" was added. Adds a default
implementation of "list" that returns nothing for backwards
compatibility.
