Test case descriptions for Tempest smoke tests

Adding a high-level description of the Tempest smoke tests.
As agreed on the last Dovetail call, we are aiming for a relatively low
level of detail and instead point to available documentation. As the
tests themselves are quite simple of read, this is the best,
most concise, and up-to-date version of documentation we can find.

+Test Area Structure
+===================
+
+The test area is structured in individual tests as listed below.
