This patch is based on https://review.openstack.org/161194 It renames vmware_nsx/tests/unit/vmware/ to vmware_nsx/tests/unit/ and creates subdirectories vmware_nsx/tests/unit/dvs/ vmware_nsx/tests/unit/nsx_mh/ vmware_nsx/tests/unit/nsx_v/ vmware_nsx/tests/unit/nsx_v3/ vmware_nsx/tests/unit/nsxlib/mh/ vmware_nsx/tests/unit/nsxlib/v3/ This is part of new vmware_nsx directory structure proposed in https://goo.gl/GdWXyH.
