make ipmid respond to SIGTERM and SIGINT for clean shutdown
On some systems ipmid was not responding to SIGTERM so systemd
could not shut it down in a clean manner, resorting to SIGKILL
after a long timeout. This adds code to respond to SIGTERM and
SIGINT and safely unwind all the provider libraries on exit.
Tested-by: running ipmid; in another shell, and running
'killall -15 ipmid' or 'killall -2 ipmid' to send
SIGTERM or SIGINT and watch that ipmid shuts down
in a controlled and timely manner.
