[CI] Stable branch CI adjustments

Xena and Yoga are past the stable maintenance
cycles. We're soon going to tag these release
branches as "unmaintained" branches [1]. We don't
expect the trunk version of manila-tempest-plugin
to work against these older branches any more.
Instead, we have tagged a "xena-last" and will
soon [2] tag a "yoga-last" branch that will be more
appropriate.

Going forward we must be testing the "maintained"
stable branches, which are zed, antelope, bobcat
as of this commit.
