Previously neutron's sidecar containers were removed only when kill-script was called with SIGKILL signal, if it was SIGTERM, then container was stopped but not removed. Now kill-script script will try to delete stopped container in both cases, when SIGKILL and SIGTERM is send to the script. Closes: rhbz#2080811 Change-Id: I79e70731779067093f6de2879b98cfe8f2b7a89f
