lvm2 is required for devstack-plugin-glusterfs to work. On debian systems, we'll require thin-provisioning-tools as well. In environments where "cinder" service is enabled, these packages are ensured by devstack since cinder defines a dependency for them. Adding these packages to this devstack-plugin will ensure this plugin can be used even without cinder enabled. Change-Id: I4990003fb603bf479326d2d7f3740eb052695f8c
