Modify kickstart templates to update the /etc/hosts and /etc/resolv.conf
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
- Provision a new host with static IPs
- Check if the /etc/hosts file contains the hostname and the IP of the new server (it's not)
- Check if the /etc/resolv.conf is populated.
/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.

It is assumed that hosts managed by Foreman have proper DNS, therefore no changes of `/etc/hosts` is necessary. Some users tend to manage hosts file entries instead of DNS, then configuration management should be used. However, feel free to send a patch to Foreman templates to do this during provisioning, but only as opt-in via parameter. By default, we do not want to change what OS installers set.
File `/etc/resolv.conf` is managed by NetworkManager from CentOS 6, there is no need of changing it directly. Nameservers must be set in ifcfg setting (DNS1, DNS2) or interactively via NetworkManager CLI, TUI or applet.
