Adding a resolv.conf configuration module (LP: #1100434)

Managing resolv.conf can be quite handy when running in an environment
where you would like to control DNS resolution, despite being provided
DNS server information by DHCP. This module will allow one to define the
structure of their resolv.conf and write it PER_ONCE.

Right now this makes the most sense on RedHat, and therefore, has defined
'distros' as such.
