    Allow setting the Koji tag extra options using the `conf.koji_tag_extra_opts`.
    
    The Koji tag extra options used to be hard-coded and to change them,
    we had to release new MBS version.
    
    We do not change them often, but right now fedora-infra is requesting
    to use new `mock.new_chroot` option and we need to release new MBS
    because of that.
    
    This commit makes such changes easier in the future.
