libvirt: Bump MIN_{LIBVIRT,QEMU}_VERSION for "Rocky" The last time we incremented versions for libvirt and QEMU was during the "Pike" release (commit: b980df0, 11-Feb-2017); for "Queens" we didn't do any. The advertized NEXT_MIN_{LIBVIRT,QEMU} versions during "Pike" release were set to: libvirt 1.3.1 and QEMU 2.5.0 -- but they weren't actually bumped for "Queens". So let's actually bump them for the "Rocky" release. Fix the affected functional tests. And where applicable, use the FAKE_{LIBVIRT, QEMU}_VERSION constants in tests, instead of hard-coding versions. Also fix the following live migration unit tests in the libvirt driver: - test_live_migration_update_graphics_xml - test_live_migration_update_serial_console_xml - test_live_migration_with_valid_target_connect_addr - test_live_migration_raises_exception In above tests the following, two main changes were made: - "Mock" the migrateToURI3() API instead of migrateToURI2() -- because with the libvirt version bump, Nova's guest.migrate() method will now call libvirt's newer API migrateToURI3() with 'params' dict. So adjust the tests accordingly. - Replace the usage of "Mox" with "Mock" in relevant tests. (I know we should try to stick to the sensible rule of "one logical change per patch". But the tests were already failing and we are systematically removing the usage of Mox in Nova source tree anyway. On that grounds, this seems reasonable.) Also drop the following version constants, which are no longer needed and adjust / remove corresponding unit tests: - MIN_{LIBVIRT_KVM,QEMU}_S390_VERSION - MIN_LIBVIRT_KVM_PPC64_VERSION - Drop MIN_LIBVIRT_VIRTUOZZO_VERSION Note that subsequent patches will handle clean up of remaining (now no longer needed) version constants and compatibility code.

The minimum required version of libvirt used by the `nova-compute`
service is now 1.3.1. And the minimum required version of QEMU used
by the `nova-compute` service is now 2.5.0. Failing to meet these
minimum versions when using the libvirt compute driver will result
in the `nova-compute` service not starting.
