disable firewalll via saltstack

[MalloZup]

Add a saltstate for disable the firewall

( we need to stop it otherwise we cannot listen from master/minion)

howto:

• create dir like firewall
  https://github.com/MalloZup/ceph-open-terrarium/tree/master/salt/srv/salt

• add a init.sls with the disable firewall

• add this state to base. ( https://github.com/MalloZup/ceph-open-terrarium/blob/master/salt/srv/salt/top.sls#L1)

At moment just disable the firewall for OpenSUSE/SUSE then we might add incremental feature for other OS.

We just stop the firewall is better
