IMPALA-3336: qgen: do not randomly generate query options (workaround) Disabling random query options seems to lessen the effects of IMPALA-3336. Since much of the memory for IMPALA-3336 is tied up in the psycopg2 cursor, and these query options are for Impala, there must be something going on in the query execution path. One theory is that so many random values for these query options don't make sense, and more queries are rejected, but meanwhile they continue to run against Postgres. It's possible the Postgres threads are not cleaning up. I haven't been able to dive into that, but let's disable this for now. We're able to get coverage without it. Moreover, I think more care needs to be given to the values chosen for these query options.
