Update tripleo-repos to match pattern

This change updates tripleo-repos to work like the other roles in
tripleo-operator-ansible and expose all the cli options as direct
vars rather than hide them. This change maintains backwards
compatibility for the version/extra_repos vars but that usages should be
dropped by anyone consuming this role.
