> This proposal is to implement: 
> "alter session cancel <execution phase> = true|false".
> where <execution phase> is an entry point for query cancellation, like say "sort" or "disk based sort" , etc.
> When this option is set, if query reaches this point, forman would issue cancel.
> This way: we can easily test correctness of query cancellation in different types of queries.
