Merge pull request #1 from sadsfae/master

fix small typo and provide example class for using the volume type for cinder/glance and swift
Removed unused comment and variables.pp
Added firewall rules for server
Removed quickstak name from example; Removed require 'puppet' from plugin type
Wrong sequence number for fw rules
given that stackforge/puppet-cinder now takes care of configuring
cinder for glusterfs storage we shouldn't include this in client.pp.
it's probably also better to include this in the respective module (cinder/glance/swift)
rather than puppet-openstack-storage.
wrap the volumes into classes
