VolumeV2 lacked functional tests for qos specs and volume type commands, so I add them. These tests are quite similar to those in v1,just three difference: 1.Importing functional.common.test instead of functional.tests.volume.v1.common 2.Adding test_volume_type_set_unset_project() in test_volume_type.py. 3.Adding a test for "qos unset" command in test_qos.py Change-Id: Ic50e8c49ef01ac967c01ec41fb3f04cd51fea9e4
