Implement changes to setup chef-server environment 

The default recipe will setup environment for chef-server.
So user can run $ chef-server-setup command to install and configure chef-server.
What else does the chef-server cookbook give us besides installing the .deb? Does it allow for arbitrary configuration? I think even if it does it's worth it for us to just use apt / yum since that is a reliable way to get a chef-server.

So I guess I support the path of not using the chef-server cookbook, at least for installing.
