Adding the dependency on nc in foreman_client.sh

puppet agent --test ends up calling "python
/var/lib/puppet/lib/facter/netns.py" which complains if nc is not
installed.  So, let's add that dependency.  I'm also hoping this
addition will prevent hangs in foreman_client.sh (I found this issue
investigating a hang).

Add Cinder to Quickstack

There is cinder_controller class which is now included from
nova_network/controller.pp.

The cinder_storage is not included anywhere yet and needs to be
manually addded in Foreman to a node. We'll want to create a hostgroup
for it.
