IMPALA-8222: disable per-query timeouts in stress test

It is very hard to pick a timeout threshold for queries
in the stress test that won't result in false positives,
because the slowdown can be non-linear with the amount
of load on the system.

To avoid this problem this change simply disables the
timeout for the stress test phase. The timeout logic
is still used for query cancellation and generating
random queries (since those may run for too long).

Testing:
Manually tested against my minicluster:
* TPC-H binary search for one query
* A short stress test run
* Random query generation with a 1 second timeout.
