This patch updates documents for aligning with OpenStack documentation standards which include using the openstackdocstheme. This patch also replaces Nova host-list API calls with hypervisor-list API calls because the former was superseded by the latter [1]. These changes are not related but squashed into one patch for passing gate tests.
