Same comments as earlier:
 - we likely want to restrict the search with ` AND ceilometer_config_environment:#{node[:ceilometer][:config][:environment]}`
 - we could use `Chef::Recipe::Barclamp::Inventory.get_network_by_type(members.first, "admin").address` instead of the fqdn (although, in this case, the fqdn should resolve on the admin IP address, so it should not be a big deal)
