Subject: [PATCH] Enable featureset override

Projects may want to override tempest runs for a given job:
 - run_tempest
 - tempest_whitelist
 - test_black_regex

Fail in case of a non-overridable config.

+Override config
+===============
+
+featureset override
+-------------------
+
+Take advantage of zuul job config to override featureset settings like
+tempest tests that should run. The following settings from the featureset
+config can be overriden:
+
+ - `run_tempest`: To run tempest or not (true|false).
+ - `tempest_whitelist`: List of tests you want to be executed.
+ - `test_black_regex`: Set of tempest tests to skip.
+
+Example::
+
+    - job:
+        name: tripleo-ci-centos-7-scenario001-multinode-oooq-container
+        parent: tripleo-ci-multinode
+        ...
+        vars:
+        featureset_override:
+          run_tempest: true
+          tempest_whitelist:
+            - 'tempest.scenario.test_volume_boot_pattern.TestVolumeBootPattern.test_volume_boot_pattern'
