File/Template file specificity: platform_family

If you could, in addition to the existing file+template specificity
functionality, make use of ‘family-<platform_family>’, would you
make use of it? Have you wished it existed?

That is, in order of precedence (highest precedence to lowest):

host-node[:fqdn]
node[:platform]-node[:platform_version]
node[:platform]-version_components
node[:platform]
family-node[:platform_family]                        <---- NEW
default

Or, explicitly:

host-web.example.com
redhat-6.4
redhat-6
redhat
family-rhel                                         <---- NEW
default
