Add ephemeral disk encryption scenario test
Adds ephemeral-disk-encryption group to Barbican Tempest configuration
options.
Enables ephemeral disk encryption for Barbican Tempest tests by updating
pre_test_hook.sh, which is run at the start of relevant gate tests.
Adds an ephemeral disk encryption scenario test to verify the
functionality of encrypted ephemeral storage. The test creates an image,
boots an instance from the created image, and writes to a new file in
the instance. Improper calls to encrypt the LVM ephemeral disk that is
being written to will be caught with this test.
