See the documentation of the Message class for a complete
description of the keyring dictionary.
*zone*, a ``dns.name.Name``, ``str``, or ``None``, the zone
which is being updated. ``None`` should only be used by dnspython's
message constructors, as a zone is required for the convenience
methods like ``add()``, ``replace()``, etc.
*rdclass*, an ``int`` or ``str``, the class of the zone.
The *keyring*, *keyname*, and *keyalgorithm* parameters are passed to
``use_tsig()``; see its documentation for details.

*replace* is the replacement mode. If ``False``,
RRs are added to an existing RRset; if ``True``, the RRset
is replaced with the specified contents. The second
argument is the section to add to. The third argument
is always a name. The other arguments can be:
- rdataset...
- ttl, rdata...
- ttl, rdtype, string...
