No ability to paginate relationships

[wtrocki]

When fetching single item I can paginate it's results but there is no pagination on relationships - fetching all of them effectively.

The same problem - when fetching tasks we are not able to filter out by open/closed tasks

check for duplicates

We have filtering on relationships, but not pagination - so going to leave this open.

WE should have done this on the schema and then later we can bring the pagination feature. This is because we need to have final non breaking schema in the 0.14.0
