    filter retired/blacklisted cntrs - fedcontainer_rc
    
    Refactoring the container release candidate code a bit and include
    a blacklist functionality for images that should never have existed
    in the first place (mostly due to growing pains in the Atomic WG
    around container best practices and guidelines, we likely won't
    need this in the future). Also add filtering for Retired packages.
    
    One thing to note is that right now this is querying pkgdb and
    datagrepper but in the future it should be asking koji about
    the list of containers in the fXX-docker-pending tag. Unfortunately
    at this time we don't have the ingress point (CI/CD test pipeline)
    to trigger an action to move containers into that tag. We will
    switch to that ASAP but this will get us moving for the time being.
