added tasks to place the config file for postfix to remove unneeded smtp headers
upadated the vagrant config to use the vagrant plugin vagrant-hostmanager. This was not an issue for production where we know what the IP address is but for the CI environment we do not know what the IP address will be.
the IP tables rules only resolve the hostname when loaded.

The ossec agent config also uses hostnames for it's configuration. But the ossec.conf is installed and managed by dpkg. If ansible overwrites a file managed by dpkg that file will not be upgraded with unattended-upgrades
