    upstream: Prime caches for DNS names needed for tests.
    
    When running the SSHFP tests, particularly on an ephemeral VM, the first
    query or two can fail for some reason, presumably because something isn't
    fully initialized or something.  To work around this, issue queries for the
    names we'll need before we need them.
