IMPALA-7517. Fix hang in scanner threads when soft limit is exceeded
As described in the JIRA, when scanner threads see that the soft limit
has been exceeded, they try to shut down. In some particular
interleavings, this would cause all of the scanner threads to exit
without any of them marking the scan as completed.
This patch adds a new fault point to inject fake soft limit errors, and
adds this fault point to the scanner test. With the previous placement
of the soft limit check, this caused query hangs pretty reliably. With
the new placement of the memory limit check, it now passes.
