"""The test suite for encrypted cinder volumes
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
NOTE (dane-fichter): These tests use a key stored in Barbican, unlike
the original volume encryption scenario in Tempest.
