riscv-koji secondary hub
    
    Here's a pull request to setup a secondary riscv-koji hub.
    
    There are still outstanding issues, but things should be
    good enough to merge and deploy the initial instance and
    interate from there. Also I plan to run a --check --diff to make sure
    there's no changes on primary hubs/etc.
