How to support offline handlers with the offset

[wtrocki]

Feature Request

When implementing pagination we usually wrap the top level types into some container to get the field offset etc. Current offix API do not work with pagination due to the need of passing root type as return. We should enable capability of wrapping objects into pagination container that is well defined and recognized when making queries so we can effectively store elements in the cache
