    package_manager.py: set dnf's releasever setting from DISTRO_CODENAME
    
    So that:
    
    1) dnf does not complain anymore about releasever not being set and then fail
    for the same reason;
    
    2) it's possible to refer to $releasever in dnf package feed configuration
    (repo paths in particular) without hardconding the release name (pyro, morty, etc.)
