Sicne 2023.1 we have started configuring haproxy backends per service
during specific playbook runtime. While it works in general, it requires
some extra steps to be run for upgrades to avoid race conditions,
when keepalived selects host as active that does not have any
backends configured.
To avoid this we suggest running haproxy with skipping keepalived
installation and proceed with backends configuration.
