Sets the certificate to be used by msg's connection when a
client certificate is requested during the TLS handshake.
You can call this as a response to signalMessage::request-certificate
signal, or before the connection is started. If certificate is null
the handshake will continue without providing a GTlsCertificate.
Note that the gio.tls_certificate.TlsCertificate set by this function will be ignored if
propertySession:tls-interaction is not null.
