    Representation of an OpenSSH-style "known hosts" file.  Host keys can be
    read from one or more files, and then individual hosts can be looked up to
    verify server keys during SSH negotiation.

    A `.HostKeys` object can be treated like a dict; any dict lookup is
    equivalent to calling `lookup`.

        Read a file of known SSH host keys, in the format used by OpenSSH.
        This type of file unfortunately doesn't exist on Windows, but on
        posix, it will usually be stored in
        ``os.path.expanduser("~/.ssh/known_hosts")``.

        If this method is called multiple times, the host keys are merged,
        not cleared.  So multiple calls to `load` will just call `add`,
        replacing any existing entries and adding new ones.

        :param str filename: name of the file to read host keys from

        Save host keys into a file, in the format used by OpenSSH.  The order
        of keys in the file will be preserved when possible (if these keys were
        loaded from a file originally).  The single exception is that combined
        lines will be split into individual key lines, which is arguably a bug.

        Parses the given line of text to find the names for the host,
        the type of key, and the key data. The line is expected to be in the
        format used by the OpenSSH known_hosts file.

        Lines are expected to not have leading or trailing whitespace.
        We don't bother to check for comments or empty lines.  All of
        that should be taken care of before sending the line to us.
