sahara: tag ocata as EOL

It has been announced on the list, and it follows the path traced

http://lists.openstack.org/pipermail/openstack-discuss/2020-October/017709.html

Also, break down the existing setting of the ocata-em branch
for consistency, and clean up a few comments which were only
needed to retrigger some tags.
