IMPALA-6352: Dump backtrace on failure of TestTableSample
TestTableSample is a flaky test which has been failing very rarely due
to a possible hung thread. Therefore this patch adds a timeout to the
test and logs the backtrace of all impalads if timeout occurs, so we
can get more information on the state of those threads.
