Kolla Train deliverables are going EOL

Dear Fellow OpenStackers, Kolla Train deliverables (Kolla, Kolla-Ansible, Kayobe) are going EOL. [1] Ussuri and Victoria remain in extended maintenance. Wallaby, Xena and Yoga are our current stable releases. The primary reason for EOLing is that the branch's CI is badly broken by Python2 and CentOS7 issues and there is no interest in fixing the issues.
