[trove-tempest-plugin] Tag yoga-last

Yoga branch is in unmaintained state now[1]. Tempest and tempest
plugins are branchless which means master version of Tempest and
its plugins is used to test the supported stable branches.

Once any stable branch is moved to unmaintained (previously for
EM) state then, Tempest and its plugins compatible tag[2][3] needs
to be released so that we can keep testing the unmaintained stable
branches with that tag.

Tagging 'yoga-last' as well as a new version with latest hash.
