This patch is changing the way how keepalived checks daemons liveness. Check_alive.sh will find checks for daemons which are copied by kolla-ansible and return 0/1 if alive/down. This patch is required for proxysql HA. Needed-By: https://review.opendev.org/c/openstack/kolla-ansible/+/770215 Change-Id: I68836918466beb572e42ffedce127747290ad481
