Description of problem:
When deploying an OSP15 undercloud, I can see errors logged by keepalived when it monitors the VIPs configured on the host:

2019-04-16T11:55:57.368030988+00:00 stderr F Tue Apr 16 11:55:57 2019: ------< VRRP Scripts >------
2019-04-16T11:55:57.368030988+00:00 stderr F Tue Apr 16 11:55:57 2019: VRRP Script = haproxy
2019-04-16T11:55:57.368030988+00:00 stderr F Tue Apr 16 11:55:57 2019: Command = '/usr/bin/test' '-S' '/var/lib/haproxy/stats' '&&' 'echo' 'show'
[...]
2019-04-16T11:55:57.371142270+00:00 stderr F Tue Apr 16 11:55:57 2019: Script `haproxy` now returning 2
2019-04-16T11:55:57.371142270+00:00 stderr F Tue Apr 16 11:55:57 2019: VRRP_Script(haproxy) failed (exited with status 2)

This is because the keepalived config uses the a script that has quoting issues and lacks call to /bin/sh:

vrrp_script haproxy {
  script "test -S /var/lib/haproxy/stats && echo "show info" | socat /var/lib/haproxy/stats stdio"
  interval 2
  weight 2
}

Note: Even if keepalived is still running, I don't think the VIP monitoring is still effective at this point.
