[goal] Keep barbican-tempest-plugin stable jobs to bionic

As per victoria cycle testing runtime and community goal
we need to migrate upstream CI/CD to Ubuntu Focal(20.04).

Tempest based jobs are migrated automatically via devstack
base job start running on Focal but stable jobs testing stable
branch needs to keep running on their supported
distro version which is bionic from train till ussuri.

Also, remove stein support (removed from tempest)
and add a job for victoria.
