to look at the new patch set (#2).
Change subject: IMPALA-13230: Dump stacktrace for impala-shell when it receives
SIGUSR1

IMPALA-13230: Dump stacktrace for impala-shell when it receives SIGUSR1
It can be useful to get a stacktrace for a running impala-shell
for debugging. This uses Python 3's faulthandler to handle the
SIGUSR1, so it prints a stacktrace for all threads when it
receives SIGUSR1.
This does not implement an equivalent functionality for Python 2.
Python 2 doesn't have the faulthandler library, and hand tests
showed that sending SIGUSR1 to Python 2 impala-shell can interrupt
network calls and abort a running query.
Testing:
- Added a test that verifies the stacktrace is printed and a
running query succeeds.
