The formula fails to check the status of the Keepalived service

[simonpasquier]

There is an issue with the keepalived formula when reapplying the state.

# salt 'ctl01*' state.sls keepalived

This is because the init script doesn't support the 'status' option:

root@ctl01:~# /etc/init.d/keepalived status
Usage: /etc/init.d/keepalived {start|stop|restart|reload|force-reload}

The error isn't happening the first time the keepalived state is applied because then it just starts the service.
But any further Salt call will fail.
