Move Cinder non-admin tests into unversioned path

As http://lists.openstack.org/pipermail/openstack-dev/2017-March/114507.html
we will use the existing Cinder V2 API tests for testing the base
microversion of Cinder V3 API also.
So it is not necessary to contain versioned path in test module pathes.
This patch just moves Cinder non-admin tests to unversioned pathes.

NOTE: v2 path still contain test_volumes_list and test_volumes_snapshots_list.
      These module names are conflict to unversioned ones, and we still need
      some works for merging them. We will follow that after this patch.
