fix Salt hostname

[MalloZup]

• The Salt master needs to resolve all its Salt minions by their host names
• All Salt minions need to resolve the Salt master by its host name.
• All minions need to resolve other minions hosts.

and all minions need to resolve other minions,
I usually generate hosts file after deployed VMs, terraform output if using terraform

@markostanojlovic i am using also terraform here,

https://github.com/MalloZup/ceph-open-terrarium/blob/master/examples/libvirt/sles12sp3.tf#L79

with that i get VMs ips.

Then i have a python script that generate dinamically the roster file and some pillar data
https://github.com/MalloZup/ceph-open-terrarium/blob/master/salt/create_roster_and_pillar.py

Basically after deploying you call salt highstate.
