Remove obsolete test code

This test code was associated with the older version of the Razor module, and
as is the nature of "bench" testing system configuration, was dominated by
useless assertions about how the module was structured.

In the rewrite the specs and other tests became essentially useless, and
rather than rewriting the testing to assert that the manifests contained what
they contained, they were ignored.

Sadly, I didn't back that up by removing the manifest content, which led to
user confusion.  So sorry to have done that to y'all.

Added an ISC DHCPd configuration example

This adds an example configuration file for the ISC DHCPd that will make it
work smoothly with razor-server.  Since we don't automatically configure DHCP
operation, this should ease integration for some folks.

This is not an example of using Puppet to configure the system, which is left
as an example for the reader.

Add an example manifest for installing Razor using `puppet apply`

This is an example of how to use `puppet apply` to install razor-server, with
a little bit of stuff wrapped around it to make it look less odd, and to try
and stop people using it in a way that might really hurt them on the master.
