[jira] [Commented] (IMPALA-6271) Impala daemon should log a message

IMPALA-6271: Impala daemon should log a message when it's being shut down
Currently Impalad does not log any message when SIGTERM is sent to
impalad to terminate or to do a graceful shut down. This change logs
a message when SIGTERM is received by impalad/catalogd/statestored.
This logging will assist in debugging the issues seen in the field
where impalad was not gracefully shut down (some other signal
was generated that led to impalad/catalogd/statestored crash).
Testing:
-------
a) Used kill to send signals to impalad/catalogd/statestored
`kill -s SIGTERM <pid of impalad/catalogd/statestored>` and see the
log message is being logged in impalad/catalogd/statestored.INFO.
b) Ran test_breakpad.py to check that existing breakpad functionalities
are not affected.
c) Ran exhaustive tests without failure.
d) Added new test in test_breakpad.py to handle SIGTERM for
impalad/statestored/catalogd.

> At present the Impala daemon does not log any message when it is being shut down, usually via SIGTERM from management software or OS shutdown. It would be good to at the very least catch this signal to log a message that we are going down. This will aid in serviceability.
