Adding storage puppet class and its dependency

1. puppetlabs/stdlib => This module is being used as is basis.
2. puppetlabs/initfile => This module is being  used as is basis.
3. stackforge/puppet-ceph => This module is been changed to handle osd differently. instead of using
	ceph-disk preapre and ceph-disk activate, a script has been written to take care of adding
	 osd to ceph cluster.
4. Storage class takes care of adding monitor, osd, keys, pools and virsh secret configuration.
	also changes to cinder,glance,nove config changes are taken care.
