Comment 1 for bug 1517412

Pacemaker log say:

    Nov 18 10:59:20 [23116] node-2.test.domain.local pacemaker_remoted: notice: operation_finished: p_haproxy_stop_0:29685:stderr [ /usr/lib/ocf/resource.d/fuel/ns_haprox
y: line 290: [: !=: unary operator expected ]

Looks like somebody removes bashisms from OCF scripts and make regression.
