Haproxy config check(/usr/sbin/haproxy -c -f /etc/haproxy/haproxy.cfg) shows a warning: 'http-request' rules ignored for backend 'galera-back' as they require HTTP mode. It's caused by the way we configure stick tables in haproxy. We don't need stick tables for galera as it has only one active backend. Change-Id: Ie41e26c1dcc671c30d39b34d3f436e225e7580a5
