This commit fixes indentations in releasenotes. Due to the indentations,
the html contents are rendered as block quotes which is awkward.

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.
