Bug Description

Observed mainly in CI on single node deployments

In some occasions (sometimes rare, sometimes more often - most often it surfaces in upgrade jobs) the standard keepalived track script that checks haproxy state via a socket - times out.
In those occurrences - keepalived fails and goes into BACKUP state for some seconds - which breaks API connectivity.

In case of multinode - there's always another node to fail over to - but in single node - not really.

    on a single node environment.
