    This test is for verifying the functionality of encrypted cinder volumes.

    For both LUKS and cryptsetup encryption types, this test performs
    the following:
        * Creates an image in Glance
        * Boots an instance from the image
        * Creates an encryption type (as admin)
        * Creates a volume of that encryption type (as a regular user)
        * Attaches and detaches the encrypted volume to the instance
