Valentin Kulichenko updated IGNITE-2546:
----------------------------------------
Description:
Need to add new method to {{IgniteCache}} API:
{code}
public <T, R> QueryCursor<R> query(Query<T> qry, IgniteClosure<T, R>
transformer);
{code}
For now this will be supported only for {{ScanQuery}}, for all others we should
throw {{UnsupportedOperationException}} with proper message.
Example and documentation should be also added.

For {{SqlFieldsQuery}} we should throw {{UnsupportedOperationException}}, but
for all other types of query proper support should be implemented.
