Tobias Schmidt 9b0091d487 Add storage.Queryable and storage.QueryableFunc
In order to compose different querier implementations more easily, this
change introduces a separate storage.Queryable interface grouping the
query (Querier) function of the storage.

Furthermore, it adds a QueryableFunc type to ease writing very simple
queryable implementations.
