Subject: [PATCH 02/12][user-cr] restart: Add args->send_sigint
restart command supports a command line option, --send-sigint to let
user specify whether SIGINT signal should be processed/ignored during
restart. Make this a field in 'struct app_restart_args' so that other
callers of app_restart() in the future can also control the SIGINT
behavior.
