Use FDQN attribute in Boundary namespace

`node[:fqdn]` is set by ohai and has a highest precedence and "can not be modified" per http://docs.opscode.com/essentials_cookbook_attribute_files.html.

This changes the bprobe name to an attribute with a lower priority so it can be overwritten.
Eg `normal[:boundary][:hostname] = 'foo'`.

Also bumped the version number to make it possible to roll out the cookbook.
