sahara-tests: release 0.4.0

Ocata support, dropping Liberty, and other updates.

Change the deliverable type to 'other', as 'tempest-plugin'
is not apparently accepted anymore. Hopefully the change
applied to old versions too will not break anything.

+        The amount of API and CLI tests was increased and made
+        more robusts (after-tests cleanups).
+        The scenario test framework now requires less parameters and on
+        the other side there are more parameters that can be overridden.
+        The time of each test phase is now clearly shown.
+        This release supports the Mitaka, Newton and Ocata releases of
+        OpenStack.
