Temporarily re-add redhat-8.yml to vars

Although tripleo deprecate master, we still use os_tempest in wallaby
and train lines, and due a design error, we rely on os_tempest master
branch instead of use the appropriate branch, and the removal of
redhat-8.yml file broken these jobs.
We will in the future, use the proper os_tempest branch on these jobs.
