Pavel Pereslegin updated IGNITE-25052:
--------------------------------------
    Description: 
Currently client resource (ResultSet) is cleared in two cases
1. User explicitly call {{close()}} on ResultSet.
2. After fetching the last page.

At the same time, javadoc of {{CancelHandle#cancel()}} contains the following 
statement
{noformat}
@return A future that will be completed after the process has been terminated 
and the resources associated with that process have been freed
{noformat}

It is necessary to implicitly clean up the client's resources when a request is 
cancelled.

Note: need to look at what other cases it is worth doing automatic resource 
cleaning (probably in the case of an error in ClientSqlCursorNextPageRequest).
