Add a new endpoint collecting the bodhi updates info for a package
    
    This endpoint returns either a JSON blob or a html table containing all
    the releases found in either bodhi or mdapi for the active releases
    (pending and stable) retrieved from bodhi.
    
    This endpoint currently only support the `rpms` namespace so it strips
    out all the flatpaks, containers and modular releases of Fedora.
