Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1416170

Description of problem:
Default kicstart finish templates are not updating the /etc/hosts and /etc/resolv.conf files. This creates additional useless effort to configure the host later via puppet or any other configuration management tool.

Version-Release number of selected component (if applicable):
All foreman releases

How reproducible:
100%

1. Provision a new host with static IPs
2. Check if the /etc/hosts file contains the hostname and the IP of the new server (it's not)
3. Check if the /etc/resolv.conf is populated.

Actual results:

Expected results:
/etc/hosts should be updated with the IP, hostname and short hostname of the new server if the IP is static.
/etc/resolv.conf should contain the DNS servers set during provisioning time.

Foreman has all the necessary information to do so, and there is no reason to write custom snippets to do that.
