> We need to support {{Statement.cancel()}} for thin JDBC driver. Ignite already able to
cancel queries on a server side, so we should simply create new request-response pair for
this.
> Special attention should be dedicated to precise specification semantics. Namely, query
could be started from the one thread, but cancelled from another. Hence, concurrency should
be implemented accurately.
