Derived subclasses usually implement a certificate selector, although they may
also choose to provide a certificate from elsewhere. Alternatively the user may
abort this certificate request, which will usually abort the TLS connection.
If the interaction is cancelled by the cancellation object, or by the
user then gio.types.TlsInteractionResult.Failed will be returned with an error that
contains a gio.types.IOErrorEnum.Cancelled error code. Certain implementations may
not support immediate cancellation.
Run synchronous interaction to ask the user to choose a certificate to use with the connection. In general, gio.tls_interaction.TlsInteraction.invokeRequestCertificate should be used instead of this function.

If gio.types.TlsInteractionResult.Handled is returned, then the #GTlsConnection passed to gio.tls_interaction.TlsInteraction.requestCertificate will have had its #GTlsConnection:certificate filled in.
