Add tests for CPU pinning. - test_cpu_shared - test_cpu_dedicated - test_resize_pinned_server_to_unpinned - test_resize_unpinned_server_to_pinned - test_reboot_pinned_server This adds some helper functions that, curiously, are not included in the base 'BaseV2ComputeAdminTest' class provided by tempest. In addition, it adds a 'bindep.txt' file and appropriate tox target to ensure the libvirt Python libraries, which this uses, are installed. Change-Id: I2eb58c886987e318f21173aac0c8fa4b410fd494 Implements: RHELOSP-12284
