This commit adds the releasenote to tag Tempest for Stein and needed for version 20.0.0 to release. This relesenote also mark end of support for Ocata release as ocata is in EM state. Once we release the Tempest 20.0.0, we will remove the ocata job from master gate. Change-Id: I93bf37e31497881536b85783dc3cff70a56b04cb
