This sets the certificate that conn will present to its peer
during the TLS handshake. For a #GTlsServerConnection, it is
mandatory to set this, and that will normally be done at construct
time.
For a #GTlsClientConnection, this is optional. If a handshake fails
with gio.types.TlsError.CertificateRequired, that means that the server
requires a certificate, and if you try connecting again, you should
call this method first. You can call
gio.tls_client_connection.TlsClientConnection.getAcceptedCas on the failed connection
to get a list of Certificate Authorities that the server will
accept certificates from.
(It is also possible that a server will allow the connection with
or without a certificate; in that case, if you don't provide a
certificate, you can tell that the server requested one by the fact
that gio.tls_client_connection.TlsClientConnection.getAcceptedCas will return
non-null.)
