Cinder has had an lvm_type option for quite a while that allows the LVM driver to be configured to use thin provisioning. This required an additional PPA in Precise, but is available in the default Trusty packages. This patch adds the lvm_type option, and we'll use it to do gate testing against the lvm_thin configuration. Change-Id: I99c7fea131f3d79747ec75052adf8b24f41ba483
