Add some functional tests for commands in VolumeV2

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
