+1 for lifting this up to AvaticaResultSet
Would be good for Avatica clients to have the standard means to cancel a
query (not hoping the Avatica server would ever get into a case where
it's not responding in a reasonable amount of time).

added a “cancelFlag” field to CalciteResultSet. Should this — and some mechanism for a running
statement to find out whether it has been canceled — make its way up to AvaticaResultSet?
Implementing cancel is a complicated issue, but this seems like a good start.
