Use a set of helper/parsing classes to perform system configuration

Previously file modification of system configuration was done
in a functional and hard to test manner. Now instead this patch
allows for a manner that provides a nice object oriented
interface to those objects as well as makes it possible to test
those parsing entities without having to invoke distro class code.
   - Created parsers for:
    - /etc/sysconfig
    - /etc/hostname
    - resolv.conf
    - /etc/hosts

Moved duplicated functionality into the root level distro class including:
 - apply_hostname
 - set_hostname
 - *various shared configuration file names/paths*
