myhostname on managed hosts is set to master node hostname

[Bartłomiej Piotrowski]

After the deployment, myhostname in /etc/postfix/main.cf is set to wrong hostname:

[root@nailgun ~]# ssh node-5 grep ^myhostname /etc/postfix/main.cf
Warning: Permanently added 'node-5' (ECDSA) to the list of known hosts.
myhostname = nailgun.test.domain.local
[root@nailgun ~]# hostname
nailgun.test.domain.local

It should be either set to actual FQDN of the host or not set all (postfix will default to current hostname).

This happens because postfix is installed during the build of bootstrap image on the master node, causing apt to pull Fuel hostname instead of not setting it at all.

The outcome of this bug is DDoS of DNS servers set in Fuel master node.
