Make the salt master also a minion

* modules/openstack_project/manifests/puppetmaster.pp: We need to be
able to trigger git pull of one or more repos on the puppet master,
which is also the salt master. The most convenient way to do this is
to make the master also a minion, so it can trigger execution of
things on itself.
