keepalived track script fails sometimes

[Michal Nasiadka]

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.

    loadbalancer: Add option to not define track script

    We've seen issues in CI when keepalived haproxy check script returns
    an error and keepalived is switching to backup and then again to primary
    on a single node environment.

    Closes-Bug: #2025219
