If haproxy is running somewhere in the cluster and listening on the VIP,
but not running locally, then the following precheck may fail:
TASK [haproxy : Checking free port for HAProxy monitor (vip interface)]
msg: Timeout when waiting for 192.0.2.10:61313 to stop.
This change fixes the issue by skipping the check if HAProxy is running
on any host.
